Mac Os X - mac os x, macmini


[Update June 15, 2010: this version of the Mac Mini has been superceded by an even slicker looking, smaller, more powerful model. Unless you can get this model at a great closeout price, I would get the newer Mini. It looks great.]



First of all my credentials, I have been writing Mac software since 1992. I've had on my various desks a Mac Plus, Performa 605, PowerBook 100, several iBooks, PowerBook G4s, MacBook, PowerMacs 7600, 8100, G3, G4 and G5, a couple recent generation iMacs and a previous generation Mac Mini. I have seen Macs come and go, and I just love this little desktop. It is exactly what I need for compiling a large desktop application using Apple's development tools. What I need is a reasonably fast processor, Firewire, 4GB of RAM and multiple monitor support. I do not need a huge box filled with disks. I do not need some super fast GPU. I do not need PCI cards. If I did, then yeah, a Mac Pro would be sitting under my desk sucking up the Watts.



My company has also provided me with a monstrous, fully loaded, Dell whose case could hold upwards of 30 Mac Mini's. In the one processor intensive task I do--doing a full rebuild of a large C++ application--the Xenon processor and desktop hard drives in the Dell can complete the task in 6 minutes while the Core 2 Duo processor and laptop drives in the Mini can do the task in 13 minutes. If I were doing that task many times a day (as opposed to several times a week) then I would need to move up to a high end iMac or Mac Pro; but I don't and I can live with the more typical single change, compile, link time of 14 seconds on the Mini versus a very erratic 6 seconds on the Dell (for whatever reason Visual Studio on the PC will sometimes take over a minute to do this).



Why is this Mac Mini a better value then the MC238LL/A at the lower price? Because it adds more RAM, a larger hard drive, and a slightly faster CPU, and I don't have to pop it open to max it out. All three things together make it worth the extra dough. If you are just going to use it for a home theatre PC, as many people do, then added expense is probably not worth it and you should go with the lesser model.



Why would you choose this over a current generation iMac? The iMacs are great machines, and can be ordered as quite the powerhouses with i5 or i7 processors, and with desktop level graphics engines, but they might be overkill and in the long run it may not make sense to be ordering machines where you can't reuse the previous machine's monitor. If you have a monitor already, the Mini will be several hundred dollars cheaper. Also, if the monitor has multiple inputs, the Mini bought today can be retired as a home server in a couple years with the Mini of the future stacked upon it sharing the same monitor. While the newest iMacs can be used as an external Display Port monitor, its still a bit inflexible tying the computer to the display. Having said this, I like the iMac too, and if you need a monitor and have the room, it may be the way to go.



Why is this Mac Mini much better than previous Mac Minis? The Mini has had several value adding changes over the last couple years: going from PowerPC to Intel, adding multiple monitor support, adding FireWire 800 support, and getting a decent GPU in the NVidia 9400M. This is a real computer. Not some dinky Ion laptop. It can do computationally intensive things, like in my case compiling hundreds of thousands of lines of C++ code. And yet it is tiny, and quiet.



So, yeah, I like this box.



What about the nearly as compact Dell Inspiron Zino HD? Well presumably you would buy the Mini because it is a Mac. The Zino is certainly cheaper, and is a valid competitor if you were setting up a home theatre PC, and could use the slightly better video card and Blueray option. If I were buying a Mini just to run Windows Media Center, I'd certainly be open to getting a Zino. I don't see an overlap between the uses of this non-home theatre Mini and the more multimedia centric Zino. I think you will find the Mini better made and faster at processor intensive operations: and it's definitely smaller.



Anyway, installation could hardly be simpler. Pop it out of the box, plug in a keyboard and mouse. It comes with a mini-DVI to DVI adaptor which will connect to any modern monitor, and you can get a mini-Display Port adaptor separately to add multiple monitor support. Power it up and you will soon be computing. It's nice, fast and quiet. Plenty of USB ports (5). Add up whatever peripherals you need: speakers, external hard drives (look at getting drives with Firewire 800, they are much faster and reliable than USB 2.0).



My wife has an older Mac Mini which she runs Windows Vista in Boot Camp mode and has done so without problem for over a year. I would think this Mini would be even better as a Windows 7 box with the much improved graphics chips allowing for better use of the Aero interface.

Artificial Intelligence - cognitive engineering, serious games


When I bought this book I wasn't quite sure what to expect since the title, "AI for Games and Animation: ..." is so broad sounding. What I did expect was that it would be written in an easy to read form and hopefully provide enough in-depth coverage of the topics so that a reasonable game programmer could implement them based on the information provided, without further research. This criteria seems to be adhered to in the technical articles in a publication such as Game Developer.Apparently, no-one bothered to tell Mr. Funge about this. Although the book does provide some case studies (examples) the actual details of their implementations are often glossed over or shrouded in unnecessary mathematical formalism that is out of place in a game programmer's book. To give an example, complex topics such as inverse kinematics and coupled spring systems are given several short paragraphs. In describing coupled spring systems for deforming a mesh, Funge uses "x dot" notation that most game programmers probably are not familiar with.The only saving grace is the reference section which can point the reader to more specific literature that may actually be helpful in constructing implementations of some of the techniques described in the book. This increases the rating from the worst (1 star) to 2 stars since it is actually pretty comphrensive. AI for Computer Games and Animation: A Cognitive Modeling Approach

The title of this book is its biggest flaw because it appears to cater to game programmers but the techniques described within it are not that useful. It appears that the book is marketed to the game programming community due to its immense size. Anybody interested it this book would be well advised to purchase the siggraph proceedings that it comes from because not only will you learn what this book is about, you will also have a large resource of other techniques that can be used for graphics and animation.Yes, John's technique is interesting and different ... however he does not have a gaming background, has never worked on games, and it is obvious that this book is simply an extension of a research paper. You can find better resources for both AI and game programming elsewhere.

This book is a fascinating mixture of perfectly reasonable AI techniques which are seldom useful for games, combined with useful but obvious techniques which are described better in a standard AI textbook.Overall, this book suffers greatly from a lack of relevance. There is no pseudocode, and the few examples in the book are poorly chosen and generally not representative of the real problems encountered in game AI programming. Similarly, many of the valuable techniques often used in game AI are not even mentioned.The book gives a brief overview of breadth-first, best-first, and depth-first search, but it entirely omits mention of the A* algorithm, some form of which is used in nearly every game that involves pathfinding.The book also covers a number of topics that are entirely out of place in a book about game AI. Chapter 2 is entirely devoted to game physics. Chapter 6 covers machine learning, a technique which is seldom used for games. And Chapter 11 covers texture mapping and deformable models, which, although important for games, have nothing to do with AI.The book does have some high points, such as the and the introduction to interval arithmetic. But even then, it wastes the reader's time with several pages of unnecessary mathematical proofs.Overall, I recommend avoiding this book. Not only will it not inform the reader, it presents a misguided notion of what game AI is all about.

The field of "artificial intelligence" is so broad, that even confining it to the domain of computer games doesn't help matters much. This book is not a cookbook on "how to write my monster code", but instead covers more of the general theory of behaviors and intelligence.I don't have a background in AI coding, so I'm not familiar with the standard AI texts another reviewer points to. Where this book excelled for me was its strong overview of AI and its applications. If you're looking for a book to hand you code for your next big game, I would look elsewhere. For a solid understanding of many of the issues of AI, this book worked quite well for me.I only gave it three stars because of its terseness and the lack of direct relevance (read: immediately usable code) for many people. For some, like myself, the book is valuable just for briefly surveying the field, allowing me to explore specific areas in more depth.

In this title, the author strives to take Artificial Intelligence to the next level. The cognitive approach is one where a character is given planning and reasoning skills with a behavioral outline and the character uses his own logic to determine its next actions. The book is designed for intermediate to advanced AI programmers, so the format of the book is quite technical (read as 'mathematics~ based'). The book guides you through such topics as, "Reactive Behavior Rules", "Hierarchical Finite-state Machines", "Precondition Axioms", "Sensing", "Embedding Goal-directed Behavior", Priority-based Control Systems", "Subgoals" and many other related issues.The book is roughly about 200 pages, and has 3 different examples for you to follow: a maze, a dinosaur world, and an undersea world. The maze is simple enough, its when you see the use of the cognitive approach in the dinosaurs and undersea creatures, that you realize the true potential of this method. In particular, I found the undersea world quite interesting. It consists of predatory sharks and merpeople. A shark will forage around systematically, going back to any spots it last saw a merperson, and will chase and try to eat any merperson it sees. Sounds simple enough. The merpeople have no weapons, but use their superior reasoning capacities to elude the 'jaws of death'. This is when things get cool. Using techniques described in the book, the author demonstrates how a merperson who has been given 'brave' characteristics will try and help a fellow merperson crying for help, as it tries to evade becoming the shark's next meal. The 'brave' merperson even risks his own cyber-life by hiding between rocks and getting dangerously close to the shark, trying to get its attention. A close call or two and the 'brave' merperson is finally able to distract the shark long enough for the other merperson to escape. The 'brave' one then leads the other back to the safety of the rocks and caves. Overall, pretty interesting reactions.When you start thinking like the author does, the whole realm of game character AI takes on a whole new meaning. Speaking of meanings, according to the Merriam Webster's Dictionary, cognitive is described as = 1 : relating or involving the act or process of knowing; including both awareness and judgment. ( from Latin -cognitio, from cognoscere, to become acquainted with, know, to come to know ) 2 : based on or capable of being reduced to empirical factual knowledge. This truly is the theory being presented in this book. It is definitely not a beginner's guide to AI, nor by any means a final authority on the subject. AI for Games and Animation is a book that helps you, the animator/ game designer, progress the way you think about your characters and how they will function for you in your next project. If the subject of AI programming pertains to you, you would be well off adding this new release to your collection. - Cognitive Engineering - Serious Games'

Yoga Accessory - hot yoga, yoga towels


I own both a Manduka towel and the Yogitoes towel and here's what I wish I would have known: The Manduka feels softer than the Yogitoes, and certainly is more versatile, since it can be used as a regular towel or even a blanket. They both feel pretty stable (can't avoid all slipping of the hands in down dog) when wet, but the major difference is that the Maduka has a tendency to bunch up more than the Yogitoes on my yoga mat during practice. The nubs on the Yogitoes do help a lot to grip the towel on the yoga mat to prevent slippage while you're jumping up to the top of the mat or performing a lunge. Caveat: I have a Gaiam yoga mat, so I'm not certain if the Manduka towel works better with the Manduka yoga mats. I have the pink Manduka - it's quite lovely and I haven't experienced any bleeding in the wash (unlike my purple Yogitoes!). But the bunching issue is really annoying, and for this reason alone, if I need another yoga towel, I would go with another Yogitoes.



UPDATE: I've since purchased a Manduka yoga mat, and the Manduka towel is MUCH better paired with the Manduka mat. In fact, I can't use the Yogitoes towel with the Maduka mat because the nubs do not grip the smoother surface of a Manduka mat very well. So in deciding which towel to purchase, bottom line is it will depend on the surface of the yoga mat you have. Yogitoes towel for your "normal" yoga mats (typically $10-$30) made of soft rubber and has a slightly nubby surface area. Maduka towel for the Maduka mats, where the surface area appears much smoother because the rubber is denser. Manduka Standard eQua Towel (Thunder)

Everyone I know who has a mat towel has one made by Yogitoes. I agonized for months over whether I should buy a Yogitoes or this. Yogitoes has those little rubber bumps on this one side, but did they really make that much difference in terms of grippiness? I use a Manduka mat and love it so I decided to take a risk and go with the Manduka towel too. I'm pretty sure it paid off. This towel feels great, you can really tell it's high quality. It's a little slippy when it's completely dry but, once damp, it provides incredible grip. I've never used a yogitoes towel so I can't make a comparison but I'd certainly recommend this one to anyone looking.

I practice heated vinyasa, so this was great considering how much i move (a lot!) and sweat (I lose about a pound and a half if I don't drink!) throughout the class. It does wrinkle ever so slightly throughout class, but not enough to be a distraction. It's more or less slip proof, but you do have to spray it down pretty generously with water before you start. In fact, the towel dries out so rapidly in the heat I have to get it uncomfortably damp at the beginning of class--but just at the spots where I put my hands and feet in downdog. However, for the price, it was well worth it--you can get two of these for the price of one yogitoes towel, and use it as a regular towel. Plus, it's a little larger than the yogitoes standard and I do appreciate the extra room.

After slipping and sliding on towels during rigorous vinyasa classes and home practice on my Jade Harmony mat - to the point where I had to constantly reposition 4 mini hand towels to my hands and feet in downward dog, to no avail - I finally caved in and bought one of these towel dealies. I went back and forth between all the options on Amazon - the Gaiam, Kulae, Yogitoes, Manduka...and in the end, decided to go for the Manduka because of reviews (noted people mentioning "quick air-drying" and no color leaking during washes) and the fact that it is significantly cheaper on Amazon than any of the yoga stores I've visited.



If you've been debating getting a towel for your yoga practice - and you're a serious yogi who can sweat a ton in classes - put it off no longer. This towel is fantastic. I can't say enough great things about it - it stays put, it's big, covers the whole mat, soaks up your sweat so there's no puddles of wet on your mat (yech), and is indeed quickly air drying. It's comfy and adds an extra layer of cushion between you and the floor (although not too much cushion for those who like to "feel" the floor) It didn't slide once during an extremely sweaty class (seriously, everyone else without yoga towels had gross puddles of sweat streaming all over the floor and mat - ew). The color and feel is soothing and even luxurious. The only possible semi-negative thing is that this towel seems to emit heat when you are lying face down (ie preparing for salambasana or locust/bow pose); it seems to echo/radiate your body heat. This to me was a very teeny trade-off for the many pluses and benefits, since I'm hot anyway regardless of whether there's a towel or not.



It also doesn't seem to soak up smell, so a simple water rinse and squeeze gets it pretty dry for next class. However, I have not washed it several times so cannot comment on its durability or continued sweat-soak ability. Will post later as an update.



You can put this on your mat in the beginning or once you get sweaty - either way, it seems to stick. A wonderful buy at a really good price on Amazon. couldn't be happier with my manduka towel!

I was unsure whether to buy this towel or the one from Yogitoes (Yogitoes Skidless Premium Mat-Size Yoga Towel). I prefer this towel -- it covers the mat better and has a slightly better feel. The difference is fairly small.



I was initially intrigued by the nubs on the Yogitoes towel, but I think they are a little bumpy and don't provide that much extra. The size of the towel makes the difference between the two.



Both towels are better wet than dry, but I still use this even at the beginning of my practice.

After doing a lot of research & finding myself torn between the Yogitoes & the Manduka eQua towel for Birkiam yoga, I decided to buy 1 of each. The Yogitoes is a bit more expensive (about $48) & Manduka about $37. The Manduka is very thin like a chamois, which was described by others this way, but one thing people didn't mention, is that LIKE a chamois, where you touch it when wet it leaves a little dark mark before it evaporates. Well, in a hot yoga class when you are sweating up a storm, the least attractive thing is wet hand/foot marks on the towel (call me whatever you like, but c'mon no one thinks that's a 'nice' benefit of a yoga towel.) Also, I found this one slipped MUCH more than the Yogitoes with the nubs. The Manduka was downright slippery. Granted it did not bunch up like a beach/bath towel, but like a chamois, it has an almost suede-like feel and during a couple of back-laying posture, I actually could slide my back up & down the mat - in a bad way. Anyway, as much as I wanted to like it, I hate it. - Yoga Towel - Yoga Towels - Hot Yoga - Yoga'

Elliptical Machine - schwinn, exercise


This is one great machine. It is very smooth,very stable and extremely well built. It took me a little over two hours to assemble and the assembly directions are very clear and well labeled with one exception. In the assembly directions, it calls for six #B screws when it is obvious they meant #A screws because they were the only ones left in the assembly process. I was worried that I would not be able to assemble it without help but had no trouble assembling it myself. For the money, I don't believe you could get any better quality even in a more expensive machine. I have very bad knees but this workout actually helps them and gives me an excellent full body workout. I recommend the Schwinn A40 to anyone. Schwinn A40 Elliptical Trainer

I'm quite happy with this machine and have already made significant strides toward my New Year's resolution of working out more often. Some notes:



- It does have a short stride length. I'm 5'3" and I actually wouldn't mind a longer stride length, but am okay with this one. People with longer legs may find themselves a bit cramped.



- The console is bare-bones. I find it difficult to read in low light, and have sometimes thought I set up a program only to discover after my 30-minute workout that it's still waiting for me to press the start button after having input all of the settings.



- The built-in reading ledge is actually perfect as a perch for my 10" netbook. I've happily watched Netflix episodes while exercising away. I don't think I could read a physical book, because there's no lip to the ledge and I'd have to hold the pages spread open, but magazines should be fine.



- I go barefoot inside my home, but can't get away with it on this machine, as there are significant indents on the steps. I ended up getting a pair of Vibram Performa shoes to get a close-to-barefoot feel without causing deep creases in my soles.



- When I'm at a running pace, the machine still feels stable but I can tell it's noticing the larger shifts in balance. I'm about 120 pounds; if you're significantly heavier, you may find it to be a bit more precarious for higher speeds.



- I can actually grab the back handle/base, lift (which tilts the machine), and pull this around without throwing out my back or anything like that, so if you do need an elliptical that you can move (short, non-vertical distances) around your house, this one may work well for you.



- It does run on batteries, but you can buy an AC adapter from the manufacturer's website.



I purchased this from a local store and had it delivered pre-assembled, so I can't comment on that aspect.



Overall, I'm quite satisfied. I wouldn't suggest it for serious runners looking for an indoor alternative, but if you just want something relatively inexpensive and don't need fancy features, this should fit the bill.

The trainer came pretty fast, but unfortunately, one part was distored. First I contact the company. It was a terribile experience, because they didn't have any parts available for replacement, cuz it's a new model. I called three times, the wainting period starts from one week to threee months. Each time, you got a different answer. The last time, they told me that You had to wait for 2-3 months for shipping from other countries.



Finellay, I called amazon, they replace the whole unit without any delay. Perfect! Amazong's customer service is far much more better that Schwinn fitness.



I'm 5'6", the stride is too short for me. I get used to those gym models with 24"stride,they burn more calories than this model. And I doubt the accuracy of the calories counter of this model.

I am a 22 year old small female, 5'4'' and 114lbs and I put this together my self in a little over an hour. Very simple! ( The hardest part was getting it out of the box, should have seen me on the floor both feet on the ends of the box trying to pull it out!) It weighs only a couple pounds less than me.



PRO's- Stable, not too space consuming, and a great workout.



CON's- Just for looks fan, barley puts any air out, Pulse grips are incorrect, and frame was a bit bent when received.



All in all I would buy this machine again for the price.

OK, to begin, I am commenting after only using the Schwinn A40 a few times so time will tell as to whether it still gets a positive rating from me, especially as to how the console holds up.



First, the order/set up. I bought this on Amazon using Prime and had it in two days....sweet! I took everything out of the box and checked to ensure all was there....which it was. The parts are easy to identify and marked either "R" or "L" which really helps on assembly and the directions are easy to understand as well. The hardware (screws, bolts, washers, etc.) comes on a cardboard sheet with each item lettered (A-B-C, etc.)and a drawn image of the item underneath. This is handy should you mix any up and in my case saved me time from a factory mistake. Somehow the metal Ex4 washers were put where the plastic Px4 washers were and vice-versa. At first I thought that the factory had not included the Ex4's but a quick comparison to the drawings answered that question.



The actual assembly was a breeze albeit around two hours as most reviewers have mentioned. It is a one person job although putting on the foot pedals is a lot easier with two. The fact there are two wheels on the front made it easy to move from the open area I assembled on to the room where it was to be used. Lift and push/pull is a lot easier than having to pick the trainer up; a definite two person job.



In my case I put the trainer on a carpet because that is where I need it. I thought from some of the other comments this might be a problem but it wasn't. The trainer is solid when you're using it, no wobble, and I didn't even have to adjust the feet for stability.



Second, are the accessories starting with the console. I took the advice of a previous reviewer and used an AC adapter that I had lying around instead of batteries. It works like a charm and I would suggest you not buy one from Schwinn; the can found for a far cheaper price at dozens of places.

Regarding the LED on the console it got a lot of negatives from other reviewers and after using it I see why.



The "readabilty" factor is not the best due to small, non-bold fonts and no backlight. Unless you have a good deal of light and a good pair of reading glasses (for some of us) it is difficult to make out many of the read-outs. Schwinn could dramatically boost the reviews on this trainer by making a more user-friendly console. That said, the built in programs themselves are more than adequate for our needs.



My last comment about the console deals with the heart monitor. It works by holding your hands around the sensors, a pair on each side of the console. When exercising I found it to be cumbersome trying to get the right grip on the monitors and getting close enough to read it while still pedaling. Schwinn should put these on the handles so you don't need to break stride just to see how your heart is doing.



Finally, the performance. I was somewhat concerned about the reviews as to the stability/performance factors some reviewers complained were poor due to their own height and weight. However, after using the trainer I can safely say it works for me.

I am a male, 5-11, 185 pounds, and the trainer handled my usage without any problems at all. The stride is just about right and the "flow" (arm movement with leg motion) suits me fine. Of course, like any new piece of exercise equipment, you need to get the "feel" of your machine and the A40 is no different. This is especially true if you have never owned an elliptical. (Think "patting your head while rubbing your belly" awkwardness at first)



As for the workout itself it is perfect for what I want: to build up cardio-vascular strength and lose a few pounds at the same time. The first program in the A40 is "Course 1" which, even after setting the minutes to only 10 and level to its lowest setting you are feeling the effects out the gate. For me that says I have a lot of latitude to increase the duration/difficulty of my exercising.



Overall, after a ton of research on these ellipticals I settled on the Schwinn A40 and so far am glad I did. For me it seems a solid machine, developed in mind for those who don't want to hassle driving to the gym, but do want a challenging workout out home. - Schwinn - Elliptical - Exercise - Affordable'

Apple Power Adapter - apple charger, apple power adapter


I received this charger 2 days after I ordered it; it shipped well, but immediately, straight out the box, the light began to flicker.

Within 15 minutes of use, it completely stopped working.



I called apple and got a replacement. You should try that. Unless you like sending packages back and getting refunds. 60W AC Power Adapter Charger For Apple MacBook Magsafe

I got the charger in the mail and it worked alright for about one day, and then started to malfunction. I would have my laptop on my lap, with the charger plugged in, and if I shifted my body or moved at all, it would stop charging. I kept having to unplug, and plug it back in for it to work. Before too long, (about a week and a half) it just stopped working all together. Just enough time had passed where I couldn't get my money back. How lovely. They are sending me a new one in the mail, but I've had to go to the Apple store and buy a new one for $85 because I needed to use my computer! Now I'll have two chargers. Great. This has all been one big headache. I should have just shelled out the $85 for a name brand product to begin with.

This worked great for two weeks, then got so hot you couldn't touch it. I was using my computer in bed one night, and sparks started to come out of the wall outlet. Not safe! I will stick to the Apple Store

Originally I had this plugged into a relatively new surge protector that sat on the floor and didn't notice anything wrong for a week or two. Then I brought it to a friend's house and plugged it into the wall only to see sparks shooting out of the charger! I've had the charger four months and now that I can no longer return it, it has stopped charging my computer even plugged into the surge protector. Not only that but it sparks when I move it, even just slightly. The tightness around the prongs and gravity of the surge protector being on the ground seems to be what was keeping it from setting my room on fire. I can no longer safely keep this product in my residence hall. I know it hurts, but spend the money and buy a new charger from Apple. It's not worth potentially burning down your house. Also, there is no way to add an extension to this charger cord.

I thought the price for a genuine Apple AC adapter was high, so I took a chance on this Brand X replacement. Big mistake! Not long past the 30-day return period, it started to work only intermittently. I had to jiggle the plug in the outlet to get a connection. Now, after less than four months of use, it does not work at all.



I wasted $22.00 on this, and ended up purchasing the genuine Apple replacement anyway.



Lesson learned.

There is a serious design flaw in the plug that connects to your computer. The cable is too small for the connection reinforcement--you know, the little rubber part that surrounds the area where the cable (wire) goes into the plug. Since the cable is too small in diameter for the reinforcement tunnel, the reinforcement does not work. IT DOES NOT KEEP THE WIRE FROM PULLING OUT OF THE PLUG. This is why they break either immediately, or very soon after the 30 day period. Like mine did. I realized there was a flaw, and used electrician tape to build some reinforcement, which helps. When it actually pulls out completely, I'll use shrink wrap to build a proper reinforcement, and reconnect it correctly. If you don't want to do that, just go buy one with the appropriate connector design.

I ordered this adapter two times and it sucks! The first time it wouldn't charge unless the computer was turned off, so they sent me a second one. The 2nd one worked for about a month before the cord near the magnet ripped! I do not move my adapter around so there should be no reason why it got so worn out so quickly!! Do not get this item!!

I ordered two days ago this charger, and not only IT IS NOT AN APPLE ITEM, but its broken and DOES NOT CHARGE MY COMPUTER. I've been conned. Absolutely UNVELIEVABLE that Amazon backs these guys. I will be expecting feedback from the seller! Because I wont even make the trip to the post office to return this.

Wire Stapler


T75 staples are UL-listed for fastening NM-B (Romex) cables. The simple design involves few jams. There are a lot of misfires and it takes a bit to get the hang of tilting the stapler lead edge forward and pressing hard just as the kick hits.



But this is WAY better than buying two-part plastic-metal staples or hammering in 'hard' staples across EVERY joist (as required in NEC). This stapler reaches places hammer-and-hard-staple cannot, although sometimes you just have to resort to screwing in a UF strap, if the clearance is too small for either.



Up there with the Klein 14/2 // 12/2 NM-B jacket stripping wire strippers, I rank this among the indispensable hand-tools of the residential electrician. Arrow Fastener T75 Wire and Cable Gun, Fits Wires up to 1/2-Inch

Being a diabetic and having very little feeling in my hands this tool works great. Using the hammered in staples I would drop 3 or 4 staples before finally driving the staple in. This stapler cut my wiring time by 2/3rd's.'

My son recently received a Power Wheels jeep that had been in use for over 3 years before he got it. The batteries had not been charged as specified in the instructions, and they died shortly after he started using it. The jeep couldn't run on concrete, much less on grass.I replaced both existing batteries with these, which incidentally are a different colour from the picture, and the jeep now runs fine on most surfaces.It requires 18 hours charging time before you can use the batteries, so be prepared for some impatience before the vehicle can actually be used. You have to charge them after each use, and also once a month if the vehicle is not in use, at 16 hours each time.Tech support from Fisher Price is non-existent in my part of the world, where 800 numbers are not accessible, because their site doesn't have a customer service or tech support e-mail address listed. I needed important information, because I learned that the model I have was recalled for electrical problems, and I wanted to see exactly which parts needed to be fixed to solve the problem.I'm sure that these batteries will last a long time with proper care, but wish the tech support was better Power Wheels 6-Volt Rechargeable Battery

This toy battery does not fit all Fisher Price riding toys even if the picture looks like it is exactly the same. Verify the battery amps NOT just volts by calling the Fisher Price toll free telephone number. Fisher Price customer service representive will be able to assist you with a local purchase option. Amazon will not accept a return if it is incorrect for "safety reasons". Verify and re-verify before purchasing.

After many failed attempts to find the right charger for the lil' quad, I finally came across a website to get the right one. Go to 1-800-sunbeam.com. It is the type A for the toddler series. Hope this helps some of you.

I bought this battery to have on hand for when my daughter ran the other one that came with her barbie jazzy jeep out. It's working out really well and it's sure nice not hearing her nagging about her battery dying and not wanting to wait for it to recharge.

Let me first state, the picture for this product is the newer fixed battery, which was replaced for certain power wheels based on a lawsuit in which a child was severely burned.



My warning is to make sure your old power wheels are not using the older batteries. the new battery as pictured has a thick black battery connector, the old ones where white and much smaller.





In my case, the barbie power wheels were recalled some time ago. A neighbor gave me their child's old one, whose batteries were from 1995. I took the 1995 batteries to a local authorized dealer, and he immediately said you will need to exchange the batteries and charger due to a recall.



Long story short, you are buying the newer, fixed batteries, which may not fit your old charger. If this is the case, I suggest you find an authorized dealer and have them replaced (batteries are not replaced for free)

There was ABSOLUTELY NO REASON to buy this battery other than THIS WEBSITE promoted it to be needed in the long run for this toy. The battery that was delivered WAS NOT compatible with the product we bought and the return AND delivery was and is a nightmare. When Toys R Us was contacted they admitted that you did NOT need this EXTRA battery and MANY MANY times the battery shipped is NOT compatible with the toy. (...)

If you have any power wheel and your kid(s) love it, then you know you need to keep one backup around. I certainly needed it. Nothing worse than the kids are happy playing and the car goes real slow and then dead.



Amazon's price for this battery is around $10 cheaper than retail stores locally. It's a no-brainer for me.

Nothing against Fisher Price, we have enjoyed their toys for years. I was extremely frustrated by my purchase however. We were trying to get a Power Wheels unit working again this spring after the winter. We weren't sure but felt it was the battery so we purchased a new one. As it turns out, it wasn't. The battery was brand new and Amazon said it would be too dangerous for them to allow us to return the product. SO, before you purchase from them be sure this is the issue otherwise you will be stuck with it. I'm sure it was in their fine print somewhere, but they refused to point it out to me.

It says you need to charge at least 18 hours before you can use it.

When I plugged it into charger it said like it is charged already, same effect with second battery.

Strange...



As well I cant understand why it says you need to charge before every new drive,

it should contain memory and based on its ni nature it is better to uncharge 100% before starting new charge at least 3 times. - Electric Powered Ride-ons - Gizmos And Gadgets - Battery - Fisher Price'
