Training Gloves


Boy have I had a hard time finding a pair of weight lifting gloves! My previous ones were simple leather Saranac gloves, not much padding but they lasted for several years. The leather eventually rotted out forming huge holes. But I can definitely say that the Saranac gloves were awesome.



Now onto the replacement. I tried four different types of gloves.



Harbinger 143

Harbinger 1260

Harbinger 1215 Big Grip II

GoFit Diamond-Trac



The Harbinger 143 gloves were OK. They didn't have too much padding, but fit very snug and were difficult to get off. Also, the fingers were short.



The Harbinger 1260 and 1215 were both unusable due to having too much padding in the palm and knuckle area. The padding is comfortable for pressing exercises (e.g. bench press), but makes it all but impossible to do pulling exercises (e.g. pull ups, curls, deadlifts, rows, etc.). You can try them yourselves, but save some money and take my word for it.



The GoFit Diamond-Trac gloves are the best of the bunch for my needs. They have a little padding in the palm, but not enough to interfere with your grip. They are lightweight, so I'm not sure how long they'll last, but I'll reserve judgment on that. They do make my hands sweat, because the neoprene on the back doesn't seem to breathe well. They run a little larger in size than the other gloves. Also, I like that they have a finger tab to help you pull off the gloves.



Please be kind enough to indicate if reviews are helpful. Harbinger 1215 Big Grip II Non-WristWrap Weight Lifting Gloves (Large)

I know others have made this comment, but the rubber grip pads on the palm of the glove are too thick and they prevent me from getting a tight grip on the dumbbell or barbell. The padding is actually welcome on exercises like bench press because it absorbs some of the weight and lets you focus more on the lift. However, on lifts that involve your palm facing down, such as dumbbell lateral raises, I cannot get a tight enough grip to feel confident that I will not drop the weight. I cannot use them at all for dead lifting because when you are pulling that much weight, you cannot afford to have a bad grip.



In nutshell, the build quality is great. They have real leather and the padding is durable. That said, they are only good for certain lifts and they fatigue your hand muscles since you are essentially, with the extra padding, grabbing onto a bar that is a bit thicker than you are used to. I had some discomfort in my forearm muscles after the first few workouts as a result.



I would prefer a glove that has very minimal padding on the palm area to act almost like a second skin rather than a padded glove. You still need to be able to feel the weights and get a tight grip to feel confident with heavy weights and prevent accidents.



I don't hate them, but personally I would not recommend them either.

These gloves look like they are great, but as many people said on here already... the rubber on the palms are so big and thick, you can barely even make a fist, let alone grab a bar securely enough for a heavy lift. I work at a gym and work out over 5 days a week, so If I cannot use these, I am assuming very few will like them.

My husband used a pair of these gloves for several years while weightlifting three days a week. They finally were in need of replacement. He had saved the packaging from the original set to ensure he would be able to replace them with the exact product. He says they are the best weightlifting gloves he has ever used and states they they give him a very secure grip.

When I got them I could tell they were not well made, not to mention the fact that one of the gloves looked and felt older than the other one. I would not recommend these gloves to anyone. They hurt the palms of my hand during presses. The idea of the rubber grips is nice but for an all around glove its terrible.

I purchased these gloves from another online vendor last week. The wrist support I would rate as moderate. My left wrist has been sore lately, and these definitely helped.



Regarding grip: Took a little getting used to at first, but I can lift fine with these. No concerns. The web of my hand gets a little sore after 45min, but hopefully that subsides once I break them in.'

Product purchased From Pro MAx Commerce was not MSA model 817628 but (model 10102485) which was not listed on the MSA web site.The product did not match the photo shown. IT did not fit my face like the 817629 and had two paper thin layers with carbon granules loose inside.The MSA 817629 mask has six layers and the carbon is embedded in a felt like fabric. If you wore this mask with a small tear inside you could breathe the granules.

1080p - 3d


I had been researching 3D TVs for over a year before I bought this TV. Plasma had my vote as lack of deep black levels were something that were very noticeable for me on my last two televisions. I had been interested in Panasonic GT25 series for a while but the cost of active shutter glasses and up-keep (battery, wear and tear etc.) was prohibitive (this being a 2nd TV in the bedroom).



The first I had heard about FPR passive glasses based devices was about a year ago. They were said to be the next best thing but being a geek who has been burned before I was initially skeptical that the 3D effect would be very good. I was certain there will be sacrifices in image quality for 2D however I was actually very surprised by the image quality (both 2D and 3D) on this television. The device simply can not be beat in terms of image quality and features at this low price (Similarly capable LG TVs (albeit with 240 Hz and some extra bells and whistles) cost more than twice as much).



I have had an HDTV (this being my 3rd) for the past 5 years and this TV has the best image quality and features and costs the least.



PROS:



- Even though this is an LCD panel the blacks levels are actually pretty good.

- PS3 and XBOX360 on HDMI look fantastic and there are several modes available to tweak color temp and/or brightness hue contrast levels.

- 3D effect looks amazing with both games and movies. I have had the TV for only a day so I have not had a chance to watch a full length 3D movie yet. 3D games I tried include wipeout HD which looks amazing. I had tried this game previously on a 3D Sony TV before and this one looks just as good while costing one 3rd.

- Lots of options are available for different settings e.g. Zoom has 4 settings (normal, wide, zoom, panoramic)

- Internet apps are available for flickr, facebook, NEtflix, VUDU, Amazon video on demand, Blockbuster and lots of news station. Not needing to power up my PS3 (for netflix) or my PC (for amazon video on demand) mean power savings :).

- Qwerty keyboard on the remote makes using these internet apps a breeze.

- The TV has wifi n and ethernet both which makes it very flexible. It has 3 HDMI ports and 1 component and 1 VGA port.

- It has capability to play songs and display pictures a usb disk (has 2-3 usb ports, I tried connecting my western digital passport and it worked great)but no movies. Pictures app has a lot of different transitions that make the slideshow and normal photo viewing great.

- The passive glasses are much lighter and more comfortable than active shutter glasses I had tried before. I wear glasses so I have to wear these on top of my existing ones and they have been much easier to handle than other glasses. I believe one can get clip-on type attachments (generic variety not from Vizio) for prescription glasses as well.





CONS:



- None that I can think of. The TV has surpassed my expectations for its price. To nitpick it is not 240HZ, or LED backlit, does not support PIP or POP. There are less options available compared to TVs that cost more than twice as much.

- After a couple of weeks of use I can definitely say that the TV is a little slow to start compared to my older HDTV, granted this one has internet apps (implying an embedded processor with an OS that needs to boot) but it is a noticeable difference. Since, this feature was not something I could test with other floor models, this could just be the norm for internet enabled TVs.



UPDATE APRIL 16th 2011:



- Confirmed that movie playback from usb disks is not supported as mentioned in the manual.

- I had a chance to watch some more 3D content (Tangled 3D, Super stardust HD, mortal Kombat 3D demo, KillZone 3 3D demo) and played around with some internet apps like Vudu and netflix and all looked great. I have not tried the wifi n link as I have it connected via wired ethernet. Vudu has a test festure built-in that tells you what format (SD, 720P, 1080P would be most suitable as they are priced differently. There are not a lot of choices though and the prices are pretty high (4.99 - 6.99 for 720p to 1080p rentals) but they are sometimes better than Sony Playstation Network especially for 3D movies.



UPDATE APRIL 25th 2011:



- Added more information and my thoughts after a couple of weeks of use.

- I also tried IZ3D with every setting but could not get 3D (for PC)to work over HDMI. Maybe it will work over RGB but for my setup HDMI looks and works better so that is not an option I was going to try.

- I would also like to add that sound quality is actually decent on this device, depending on the source of the original material sound is clear. I was going to buy a sound bar for this TV (since it is in my bedroom) but i guess i can wait until the next version comes out in July instead of buying last years model. VIZIO E3D420VX 42 Inch Class Theater 3D LCD HDTV with VIZIO Internet Apps

I was impressed with how well this TV produced flawless 3D effects without any ghosting at all. 3D Blu-ray movies appear brighter and even more rich in color through the polarized glasses. As opposed to some of the active shutter glasses I have tried out, the lightweight polarized glasses are less strenous on both the eyes and the nose they rest on. The TV also works well with the PS3 and generates an immersive 3d gaming enviroment. While I was easily able to link my computer to it through the hdmi port to play my downloaded 3d content, I was a little dissapointed that I could not access 3d controls while trying it on the RGB port. I also could not find a way to make it work with nvidia's 3d vision. However, I am hopeful that Nvidia will provide support for this TV in a future driver release. The TV can normally autodetect 3D content but when it doesn't you can push the 3D button on the remote for easy access to the SBS, TB, or Sensio 3d settings. The wireless setup was very quick and easy and involved no more then picking out my network and typing in my password. I also really like the one touch buttons for VOD, Netflix, And Vudu. The full QWERTY keyboard on the reverse side of the remote allows for painless browsing of online movies and TV shows. In conclusion, for the features, screen size, quality and price of this TV set, it's a fantastic bargain and I fully endorse it.



IMPORTANT NOTE -- When using the TV for gaming, make sure film mode is off or you will experience massive input lag.



Update: after a bit of tinkering I have found that the TV works flawlessly with IZ3D drivers on the interleaved setting, you don't even have to put the tv in 3d mode for it to work and it produces some truly amazing pc 3d gaming immersion. Don't even bother with nvidia 3d vision its a dead end on this tv, the IZ3D software works with both ati and nvidia cards. - 3d'

Video Games - adapters, pc vga to tv converter


The other reviewers did not read the first sentence in the description. Your computer MUST have TV-Out capability for this cable to work, which is rare. You cannot simply connect this cable between your computer and TV and expect to get a signal. It's unfortunate that this product got so many 1-stars due to customers not doing their homework.



This cable works great if your computer has the TV-Out capability but if it does not, then you must purchase a VGA to S-video converter in the $30-60 range. NEW VGA to TV CONVERTER S-VIDEO+RCA OUT CABLE ADAPTER (only for graphic card have TV Out function)

First off, this cable DOES NOT convert your video signal. In the reviews below, no one (except one) knew what they were doing. TVs in America are NTSC, not VGA. If you plug the cable into a PC that doesn't output an NTSC signal this isn't going to work on your TV. Its like trying to get a 1080p HD signal on a SD TV from 1983; it simply isn't going to work.



Also, if your trying to connect your Xbox to a computer monitor, get the VGA output for the Xbox. It works like a charm. Same example as above except vice-versa. The Xbox is putting out an NTSC signal when you use the component cable but the monitor wants a VGA signal.

MOST DO NOT

Your computer MUST have TV-Out capability for this cable to work, so check with your cards manufacturer.



That would have save the reveiewers below some money and some posted lies about the product.



Everyone blames everything and everyone else for their errors.

Read the product description!! This product will NOT work with most video cards. I made the mistake of not checking to see if my video card had TV-out capability, and this product did not work for me. If you want to view your computer on the TV, buy a converter like the Lake PC to TV Converter Box compatible with Windows and Mac (VGA To RCA / VGA To S-Video) (I just bought one and it works like a charm :)

I do not think that there is anything wrong with this product. It supports a video card that will send video through the VGA port suitable to be picked up by the S-Video or Composite (RCA) inputs of a TV. I tried it on two laptops and it did not work for what I believe is the reason stated above. When I connect the computers to an external monitor via the VGA port they pick up the external monitor right away. One of the laptops has a S-Video port and it works great on any TV.

So, a quick call or email to the manufacturer of the video card in your computer or the manufacturer of the computer may avoid some disappointment. Many of the reviewers on this and other sites have made the same claim :-). I will buy a VGA to TV converter; they are available for as low as $40 and will provide the connectivity and flexibility that I need. I just have to write this one off as being a cheap experiment.

Everything is right with that adapter, but my HP mini netbook just did not have the correct video card, which would support TV s-video out. I was misled by HP technical support people. I was shocked how unprofessional these people were, they weren't familiar with their own product. They consumed a lot of my time for nothing. Finally I needed to by PC-TV converter for $30 anyway, so I resolved my problem. My advice is, make sure first that you PC have a correct video card, then decide what you need to buy.

Hey I have purchased new Inspiron 15R laptop and the Dell technical dept told me that VGA has TV out capability, so went on to purchase this product... In vain its not working at all no images are displayed on my TV... Please give my money back.

it was a long shot for me, hoping I would be able to use my computer on my tv like a lot of people here but i knew my chances were slim but it was cheap enough that I didnt care it didnt work for me. but thats no reason to rate the product bad.



MC

The seller advertises this as an CONVERTER when it is really an ADAPTER. This is misleading and the reason for the many negative reviews. There are many true computer VGA to TV converters for sale but this is NOT one of them. To get a vga signal from your computer to a tv to work, you need a converter, not an adapter. I wish the merchant would be more realistic in his description. I give it a two, because there is nothing wrong with this cable, but it is advertised wrongly. - S-video - Pc Vga To Tv Converter - Adapters - Laptop To Tv'

Rechargeable Batteries - nimh, eneloop


[Updated Oct 24, 2008]

My original review on the Sanyo eneloop NiMH cells was written nearly two years ago. Since then, I have learned a lot more about the characteristics about eneloop and other low-self-discharge cells. So it is time to clear up some inaccurate information I wrote about eneloop's self-discharge rate.



1. I was told that the Sanyo eneloop cells were not 100% fully charged when they leave factory. This makes sense because new cells are fast-charged in the factory to save time. In order to avoid problem with heat and gas built-up, they cannot be charged to 100%. I have tested some eneloop cells that were manufactured 20 months ago, and they still maintained about 70% charge. On the other hand, cells manufactured 6 months ago contain about 75% charge. This confirmed that the discharge rate is much lower than I previously estimated.



2. The self-discharge rate of eneloop (and other LSD cells) is not linear! My own testing showed that a fully charged eneloop may lose 10% of its initial charge during the first month of storage, but in the second months it may lose just 2-3%. The rate becomes even slower after three months. In fact, my 5-month self-discharge test using various brands of LSD cells gave nearly identical results as my previous 3-month test.



3. When an eneloop cell is freshly charged, its capacity actually measures at about 5% higher than its rated capacity (2100mAh vs. 2000mAh). In my previous tests, I used measured capacity as base to calculate the percentage loss. This results in apparently higher percentage loss. Had I used the rated capacity as base value, the self-discharge rate would be about 5% lower.



Based on the above revelation, I believe Sanyo's claim about eneloop (maintain 85% charge after one year, 80% after two year) to be accurate. Therefore the title of my previous review ("The News of LSD Has Been Slightly Exaggerated") has to be replaced.



Over the past two years, I have tested several different brands of LSD cells available from Amazon.com, including Rayovac Hybrid, Kodak Pre-Charged, and Duracell Pre Charged. They have all performed very well - practically no difference from the Sanyo eneloop. So the bottom line is: just pick which ever brand of LSD cell is on sale, and you can't go wrong.





[Update on April 21, 2011]

- After testing and using various brands of LSD cells over the past four years, Sanyo eneloop cells have proven to be the most reliable and consistent of them all. I now have to recommend Sanyo eneloop over all others brands.



- Recently Amazon started to offer the SANYO NEW 1500 eneloop cells, at around 25% higher price. In my testing, the improvement of the new eneloop over the original is hardly noticeable. So you'll have to decide whether it is worthwhile to pay the extra cost. Sanyo Eneloop 4 Pack AA NiMH Pre-Charged Rechargable Batteries w/ Charger

[IMPORTANT NOTE]

My original review below was written back in 2007, when the Sanyo eneloop first became available

through Amazon.com. Part of my initial estimation about eneloop's self-discharge rate turns out to be inaccurate. Please see my other Amazon spotlight review for updated information.



[Original Review follows]



According to Sanyo, the new eneloop LSD (low self-discharge) NiMH batteries can maintain 85% of its original charge after 1 year of storage. This claim is slightly misleading, because it is based on simulation test at 20 degree C. At higher temperature, the self-discharge rate is likely to be much higher.



I have tested five of those AA cells (details are given in my review for the eneloop 4-pack). The average energy loss is about 26% after less than 6 months of storage, based on manufacturer date codes. This self-discharge rate is about 3 times higher than what Sanyo claimed. However, it is still 6 times lower than that of ordinary NiMH batteries. Therefore I'm in the process of replacing most of my existing rechargeable cells to the Sanyo eneloop.



Thanks to lower self-discharge rate, you'll discover a lot more applications for eneloop cells in your house, such as in clocks and remote controls. Do NOT use those cell in smoke detectors, since their discharge voltage profile is very different from that of alkaline cells. Also, don't use them as emergency flash lights batteries in your car, because the higher temperature during summer time will probably nullify the advantage of LSD.



[Update on Jan 13, 2007]

I have tested six new eneloop AAA cells, dated "2006-06'. The average residue charge is 589mAh, and the freshly charged capacity is 827mAh. This implies a self-discharge rate of 29% in 7 months, which is consistent with the rate for AA cells (26% loss in 6 months).



[Update on Jan 29, 2007]

The Rayovac "Hybrid" rechargeable NiMH batteries are now available at Walmart, priced at only $[...] for 4-pack of AA or AAA cells. It is also advertised to have low self-discharge rate, but not as low as that for eneloop. The eneloop is supposed to retain 85% charge in 12 months (when stored at 20 degree C), whereas Hybrid is supposed to retain 80% charge in 6 months (no mention of temperature).



[Update on June 3, 2007]

In my 2-month self-discharge test using four different brands of NiMH cells. Hybrid and eneloop came up neck-and-neck!



Room temperature: 60-62 degree F (16-17 degree C). All capacities measured are average of 2-cells.



- Sanyo eneloop 2000, purchased Jan 2007.

Initial capacity measured: 2070mAh

Capacity after 62 days: 1796mAh (-13.2%)

(Note: my previous result for eneloop showed -18%, but I repeated the test and it did better this time)



- Rayovac Hybrid 2100, purchased Jan 2007.

Initial capacity measured: 2155mAh

Capacity after 62 days: 1859mAh (-13.8%)



- LaCrosse 2000, purchased Jan 2006.

Initial capacity measured: 1902mAh

Capacity after 62 days: 1417mAh (-26%)



- SONY 2300, purchased Sep 2004.

Initial capacity measured: 2210mAh

Capacity after 62 days: 1309mAh (-41%)



So neither eneloop nor Hybrid did as well as advertised, but they are still significantly better than previous generation of NiMH cells. So you can't go wrong with either brand. - Battery Charger - Eneloop - Battery - Nimh'

Latitude Wiper Blades - rain-x, latitude wiper blades


Reading some of the other reviews, I think some people are installing these incorrectly. The symptoms they describe sound like the first set I bought, which was for my girlfriend's 2008 Nissan Rogue. When I installed the driver's side wiper (the longer of the two) it didn't make good contact with the windshield and would have left huge streaks. There is a way to adjust how the wiper sits by fiddling with the mount. Once I did that (per the included instructions), it worked like a champ. I just put a pair on my 2010 Xterra, and didn't have to do anything special...they worked great from the start. It sometimes pays to read the instructions.



As far as the blades scratching the windshield, the only thing I can think of that would cause that to happen is if they forgot to take the plastic cover off the blade. I can't see how someone might do that, but the blade itself is pretty flexible, so I have no idea how it could scratch auto glass.



For me, these have been great, and the price on Amazon is very reasonable. I think I saved about $6 per blade by not getting them at the local auto parts store. I think this should be one of the items that Amazon lets you "Subscribe" to, so you could have them delivered every six months or so. That would certainly help me to remember to change my wiper blades! Rain-X 5079280 Latitude 8-In-1 Premium Graphite Coated Wiper Blade - 24"

These wipers are fantastic in the rain, especially when brand new. They do not squeak or smear while removing all water from your windshield.



In the snow, they are not that bad, if you park your car in a garage anyway. The problem with these blades is that they do not hold up well in cold weather, especially when coated with snow and ice.



I've had these blades on my Blazer for about 7 months, and during the fall they were great. Once the bad weather started to come (Buffalo, NY) the snow and ice began to build up on the blades while parked outside. The design of these blades includes plastic end caps that keep the main blade strip from moving. But when water has collected inside the cap and it freezes, the expanded ice loosens the cap and it eventually falls off. After that, the blade will slowly ease its way out from the holder slot. If you do not slide it back right away (every day or during the drive) it will ruin the blade when it wipes. This results in the wiper not being able to get a clean wipe in thick snows or sleet on both strokes. I regularly get a big wet icy patch in the middle of my windshield due to this.



I have been looking for the perfect winter wipers for a long time, and these are not them.

The Rain-X Latitude wiper blade promises advanced visibility through simplified design. Gone are the springs and hinges that conventional wipers use to try to keep the blade on your windshield. The Latitude is basically a floppy graphite-coated blade that molds itself to the shape of your windshield, promoting more uniform contact, pressure, and as a result, visibility.



I've been using mine for several months now and have always been pleased with their performance. They're definitely quieter than any other wipers I've ever used and they do eliminate those annoying streaks of rain/ice/salt that can form when conventional wipers start to break down.



Installation was supposedly simple, but the mounting clips that were provided were ill-fitting. Plus, they're made out of lightweight plastic that felt very cheap - I was afraid that I'd break them while trying to fit them to my car's wiper arms. I finally gave up and had my mechanic put them on since I had a routine appointment coming up anyway.



My only ongoing concern is how long they'll last given the plastic mounting clips and the soft, delicate feel of the blades themselves. I'll update this review if I run into any trouble, but so far so good.

When I received these wipers I was pretty excited about the design. They are basically a sturdy curved flexible one-piece body with a graphite rubber wiper blade attached. They curve that is build-in seems to be a good solution to replacing all of the little metal springy parts that make up a conventional wiper - fewer parts to catch ice or snow.



I installed these on my '03 Tundra and found that when the curve of the wiper was pushed into the curve of my windshield it failed for about 1.5" of wiper on the far right of the passenger window wiper. This small portion just floated over the window - in some places wiping - in most places just skimming the water, not really touching the window.. This was also happening to a lesser degree on the driver's side. The result is unsatisfactory, as the missed water tends to cause running before the wiper cycles again. I switched sides and got the same results.



I am going to try to intentionally deform the wiper end that is not contacting the window but I'm afraid the verdict is in for me. These may work just fine for your vehicle but '03 Tundra owners, consider yourselves warned.

In cold weather one wiper worked in one direction of sweep then did not "flip" over and change direction for the opposite sweep. This caused a chattering and rappid skipping.



The other wiper simply did not make complete contact with windshield.



These might work in a warm weather climate.

I had Bosch wipers on my VW Passat and they never really cleaned off the windshield well. I've had the 20" Latitudes on for two month in a typical New England winter (rain, snow, sleet, more snow) and they've worked like a charm. I would recommend them over Bosch, they are more substantial and look cool too.

So, this was my first attempt at the "contemporary" wiper blade design and I have to say I was extremely disappointed with the Latitudes. Right out of the box they were streaking on me. The driver side wiper was leaving a huge smear patch in the middle of my line of sight. They were very quiet, but just didn't seem to hug the windshield at all. I have since moved to the Bosch Icon's and they are a far superior product in my opinion. - Wiper - Latitude Wiper Blades - Wiper Blades - Rain-x'

Lithium Battery - battery packs, lithium-ion


I have owned a set of Makita tools with the LXT batteries for a couple years now and I have noticed absolutely zero power loss or any other problems. I use them quite regularly whether building concrete forms, decks, remodels, etc. I can think of three things that may be happening to the batteries of those who have commented on bad performance or longevity; (1) Occasionally, batteries can be bad from the factory (I have yet to own a milwaukee tool with the new "V" or "M" series battery that holds up past a few months. I have both V28 and M12, and have had ALL packs replaced) (2) It is possible to have a bad charger which is damaging the batteries itself, or (3) Perhaps the users are taking them all the way to the point of stalling and complete discharge, and for that the batteries are truly not made to do. It is best that once you notice the battery pack is wearing down, to grab a fresh one and put the discharged on the charger to cool down and refresh. Also, if the batteries are being stored for most of their life, it is best to keep the charger plugged in and rotate batteries through it to keep everything active and refreshed. Lithium batteries have computer chips and sophisticated circuitry, allowing them to constantly be charged without damage. Ni-Cad on the other hand are not supposed to be charged over and over again because they typically have memory effects and lifetime charging limits. It is best to mostly, not completely, discharge a Ni-Cad before replacing back onto the charger. Because a consumer only has ultimate control of this last variable, it is a good idea to read the owners manual and find out what the manufacturer thinks is best operating practices. Only those who are using the batteries and tools know how they are being treated, and you may very well be doing everything right and not fall into this third category. Being that my kit is from a couple years ago, and my newest battery packs (purchased just for continued use because I have many LXT tools) were purchased last year sometime, it is possible that the newer batteries are of a lesser quality, and that would be unfortunate. What I can say is this; I own many Dewalt tools, which I have only had to replace a couple Ni-Cad battery packs in the past 5 years. (Dewalt tools are mostly made in Mexico) I have owned MANY Milwaukee tools in which their Ni-Cads held up pretty well, but their Li-Ion line is absolute crap. Several years ago when their tools were still made in the US, their quality was impeccable. Their tools are now made completely in China. (Yes, many of the Makitas are also) I own several Bosch as well, and their batteries and tools are right up there with Makita's quality. As far as Skil, Black and Decker, and any other cheaper or knock-off brand goes, I would personally never purchase them. For one, you are supporting China, and secondly you would be purchasing a tool that is undependable. Hitachi has an excellent warranty, and makes excellent air nailers, however I'm unsure of the quality you may find in their power tools, both corded and cordless. I hope this was helpful. Makita BL1830 18-Volt LXT Lithium-Ion Battery

Really, these batteries provide seemingly endless power. They hold their charge for weeks with very little loss. I can use one battery for drilling and driving throughout an entire (moderately sized) project. They are extremely lightweight and charge in twenty minutes or less usually (in hot weather it takes longer). All three of mine slide on and off easily, with no issues of binding or falling off. With all the praise comes a VERY important caveat. DO NOT run these batteries into the ground. The instructions state that as soon as you notice a loss of power, stop and charge. If you over-discharge Li-Ion batteries, you can seriously degrade the life of the battery. These batteries are 1/3 cheaper on Amazon.com than at the home centers, so buy from here! Also, only the cells themselves are made in Japan, all other parts are made and final assembly is in China.

I love the drill but the battery life is a real problem. I had both original packs replaced under warranty when the charger reported them bad. Now one of the replacements is flashing bad on the charger. These have been cycled maybe a dozen times. I'll be complaining to Makita and also reporting this on the various woodworking groups I support.

I replaced a 14.4 Milwaukee NiCad with a Makita LXT and noticed that my old Milwaukee NiCads outlasted these in terms of longevity. Run time is solid, but lifespan is short. Two dead after one year, I'm only a homeowner. I've only done a few lengthy jobs such as putting cement board down in a 10x20 room, and building a deck with these, in addition to the other basic tasks of drywall, and other light construction needs. Love the light weight though. Now, I need new ones. Somewhat disappointing.

I went ahead and invested in a pair of these batteries despite the mixed reviews, figuring I'd at least get a year out of them with the warranty. So far, they've performed just fine, even on tools that are supposed to only use the BL1830. I mostly use them on the BHP454 drill (note: this is one of the tools that's keyed for the 1830 pack) and BTD141 impact driver when I'm not going to be using them for long, so the decreased runtime doesn't bother me. I also use them on the angle grinder and recip saw (after removing the little tab on the tools) for light work in tight spaces. I wouldn't want them to be my only batteries, but they're a great addition to a couple of the larger batteries if you have a few tools that can use them.



These slim packs are very handy on the drill, impact, and flashlight- the lighter weight and smaller size are noticeable, especially with the smaller (BDF/BHP452) drills. However, buyer beware when it comes to using them on the 'heavier' tools, as they are keyed for the larger batteries because they can draw more current than these smaller batteries can provide without damaging the cells. So you probably shouldn't slap one of these on your circular saw and go ripping 2x12s all day, or you'll kill the pack very quickly. Makita isn't trying to screw you into buying more batteries, they're trying to make sure you don't kill your batteries.



Another note, considering how many complaints of defective packs there are: don't run these batteries down to nothing, and try not to store them fully charged. Running them into the ground is a sure way to damage the cells, and I've read estimates of up to 20%/year capacity loss for a fully-charged pack, compared to as low as 2%/year for a pack stored @ 40% charge.



And of course, like any cordless tool/battery purchase- shop your options before buying batteries separately. I got the BHP452HW kit for only $50 more than 2 batteries. That's a cheap, easy way to have a spare drill or driver and charger for around the house, or to sell to recoup the extra cost.



I'm knocking off one star because Makita doesn't do a good job of letting people know that these slim packs only work on certain tools- and not very many, either. That's been a complaint for years now, and it's still not mentioned anywhere in their literature or website- even my local Makita dealer didn't know they weren't compatible with all LXT tools. It's not like it's standard practice- Bosch's and Milwaukee's slim packs fit their entire lineup, AFAIK. - Lithium-ion - Lithium Battery - Battery Packs - Makita'
