Electronics : American Weigh 600g x 0.1 Digital Gram Coin Pocket Scale Mini Accurate Gold

Rating: - same object, different weight every time
A quarter produced readings anywhere from 4.4 to 6.4 grams. The same small jar gave readings from 109.8 grams to 113.3 grams.

Presumably I got a lemon. I only paid the $7 price plus shipping. Can't report on return or exchange experience as I haven't bothered to try yet.

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 got this scale to keep at work for when there are treats, etc. so that I could keep track of what I eat. It works great and fits in my drawer. I believe it is pretty accurate, no problems. Comes in very handy.
