I bought this unit to weigh gold and silver coins and bullion. It's a very sturdy yet compact unit. It fits in a pocket or purse or any bag. It seems to be very well made and the scales are accurate.
When I first got the unit and turned it on, it didn't work. I discovered the batteries were loose. Actually, the batteries should be outside the unit when shipped.
In any case, while I've not owned them long, I'm very pleased with them. The price is exceptional and EZ Sales are just super to deal with.
I was a bit annoyed that the unit did not come with a calibration weight. Be sure and get the 500 gram weight for this model. You won't need it the first time you use the unit, but at some point, you will.
Highly recommended.
Update: After using the scales for checking coin weight for awhile now, I've noticed that it's not totally accurate. Even after calibration. A silver dollar should weigh 31.1 grams. I have them weigh from 31.1 to 31.5. But the troy ounce is always 1oz, as it should be.
There is a margin of error. So if you need extreme accuracy, you'll have to spend a lot more money. But if you want to be just quite close, this will do fine.
I ordered this scale to weigh small parts for RC cars and it has performed excellent. As others have mentioned you need to remove the batteries from the unit before using the scale because the batteries are shrink wrapped in plastic. For the price I didn't expect the build quality to be great so I wasn't shocked at the fairly cheap build quality. The plastic casing feels ok but the battery cover feels cheap and loose. The protective cover for the stainless steel weighing platform is not too bad though. The scale is small about 4" x 3" in size but the weighing platform is decently sized covering about 70% of that area.
In terms of ease of use and accuracy it's a great little scale with a nice sized backlit LCD with an auto shutoff to conserve battey power. To get accurate results you need to place it on a flat non-moving surface because this scale is VERY sensitive. I've found the scale to be very consistent by weighing the same objects many times and the results were always within +/- 0.1 grams for small items that are less than 30g. The scale comes ready to use and calibrated from the factory, however if you ever need to recalibrate this model you will need to use a 500g calibration weight, you cannot use smaller calibration weights because they will not calibrate correctly. Also keep in mind that environmental factors will affect the scale readings such as ambient temperature, strong drafts from ceiling fans and magnetic fields.
This is a precision instrument so should be adequately taken care of eg don't drop it, don't let it sit in direct sunlight, don't keep it in high humidity areas and also store the scale lying flat not vertical. All in all a great low cost and accurate pocket sized scale that is very easy to use.
The price was excellent. The scale works well, and I haven't noticed any of the inconsistencies noted by other reviewers.
The clamshell cover and stainless steel scale plate are excellent features, as is the 'indiglo-style' backlight to the display, which was an unexpected, though very welcome, surprise, and the batteries were included (also a nice surprise these days).
I, too, noticed that the batteries were crooked and the unit didn't work immediately when I opened the package, though this appears to be deliberate to keep the batteries from draining while in transit. Once they are unwrapped (mine were shrink-wrapped, and installed in the scale fully wrapped), the scale works fine.
All in all, it is very nice, quick and easy to use, and took precisely two days to get to me with standard shipping -- astoundingly fast service.
I'm very satisfied with this purchase.
The scale is constructed quite nicely, and the black casing with stainless steel weighing pad adds for a nice polished look. It comes with batteries (which I discarded because they were a nameless Chinese brand) but the thought of adding batteries free of charge is nice. In the battery compartment there is a place to store an extra set of batteries (which I do, it makes it feel weightier/higher quality). It's very slim and is easily stored. Instructions are printed on the inside of the lid which is nice. Another reviewer said not to calibrate it, but I purchased a 500 gram calibrating weight and did it just to see if it would work okay and it did. The scale said 500.6 grams before I calibrated it, so it was fairly accurate to begin with and most likely won't require calibration for a while. Good looks, accurate and repeatable results, excellent price, what more could you want in a 600 gram scale?
When it was working it was flaky. It would weigh the exact same thing out differently . (Margin for error was about .2 of a gram for every 5 grams on the scale.) After just a few uses, It said the batteries were dead. (came with some cheap generic chinese batteries) When I opened up the compartment, one of said batteries had been leaking battery acid all over the inside of the scale. Needless to say all the metal parts were rusted out and it never turned on again. BUYER BEWARE THIS IS A SUB PAR PRODUCT. - American Weigh - Jewelry - Digital - Coins - Kitchen Scale - Pocket Scale'
