This scale is a great value for the .01 gram precision it offers. Once calibrated it is quite sensitive and accurate. Mine came quite far from calibrated, but based on the other reviews here it appears this is only a fluke. The scale is lightweight and very portable, being roughly the same size as a Nintendo DS Lite. Build quality is good; it looks like it will last a long time if used properly and carefully. Comes with two AAA batteries and a space for storing a pair of extras. Very nice scale for the price.
One hint about calibration: if you forget to buy the 100g calibration weight, you can simply use 20 U.S. nickels, as each nickel is exactly 5g.

I purchased this device so that I could measure the minerals that I add into 'pure' water. The idea is that my local tap water is toxic to the fish in my 55 gallon aquarium, so I use reverse osmosis water. RO water has no minerals, fish need some, so I enjoy being able to measure out mineral additives to a .01 gram resolution.
I did test this with a hand full of coins (and the US Mint weight chart) and all came in within .04 grams (coins vary).
I did buy the 100g calibration weight. As it turned out, my device was calibrated 99.99% out of the box. Nothing wrong with that.

I've had this scale for a couple years, and I'm very happy with it. It's accurate, repeatable +/- 0.02 grams on different days, and has held up through moderate handling (nothing abusive, but stuff that I'd never put my lab scale through).
It uses what I call a "floating zero". This is good and bad... When within 0.03 grams of zero and steady, it displays 0.00 and slowly adjusts its zero. If you slowly add 0.01 grams at a time, you can get it to drift way off, and when you eventually take off all the weights at once, it'll display -0.20 grams or whatever their weight was. The good is that the scale, despite its inexpensive mechanism, keeps very good zero calibration between measurements. The downside is that it makes small measurements difficult. If you want to weigh out 0.15 grams of powder, you can't just tare your weigh paper and then gradually pour it on - the zero will drift unless you add the first 0.05 grams quickly enough. Instead, you can NOT tare it, and manually subtract the weigh paper.
This feature is not a problem at all unless you're weighing very small (less than 0.1 grams) items on a regular basis. I think this is an acceptable compromise for a pocket scale of this precision at this price (and it's practically standard until you get to much more expensive equipment), so I am not marking any points off.

This is an ideal scale for coin collectors, jewelry or any need to weigh small items under 100 grams. I used to work in an engineering lab this has a real nice instrument grade feel it is not a toy. At reasonable price you can weigh to 0.01 gram other pocket scales only weigh to 0.1 gram. Has Gram, OZ, Carat, Grain and tare weight modes very easy to use and portable. Don't forget to order the 100 gram calibration weight also. You will not regret this purchase.

I bought this precision scale and calibration weight set specifically so that I could tell whether a clear round brilliant cut gemstone that I have was a real diamond or a synthetic diamond. I measured the diameter and depth of the stone with a caliper and then used a mathematical formula to determine what the gem SHOULD weigh if it were a diamond perfectly cut, which was a little over 1.97 carats. Then I used the scale to weigh the stone. It weighed 3.4 carats, meaning that it's cubic zirconia, which has a specific gravity much higher than that of a diamond.
Oh well, at least I know for sure, instead of having to trust a jeweler to tell me the truth about it.
By the way, this scale is quite small and light, can use several different units of measure, and arrived with batteries installed and ready for the calibration to be tested and the scale to be used.

DBRoth provides the one piece chrome calibration weight as pictured, in a plastic carrying case. I saw in reviews of other vendors that the 100g weight provided was inferior and in one case, missing a screw-on handle (!). The scale is very nice for a variety of uses where precision is required, and the sensitivity to measure grains at this price is an outstanding value. Readout is bright and and calibration is pass/fail, a nice feature imo.

I bought this to weigh polymer clay for forming beads. It's very sensitive, it can detect a small scrap of plastic wrap. It has a tare function if you need to use a piece of paper as a carrier for what you are weighing. The actual scale plate is small (2 1/2 by 3 inches), and the weight limit (100 grams) is also small,so it cannot handle a large object. You could weigh letters, but not packages. Very easy to use.

I collect tobacco pipes and blend pipe tobacco for my own use, and I needed a small digital scale for measuring out the differant tobacco's. I originally bought the 100 gram scale but realized that I should have purchased the 600 gram scale for weighing larger amounts.I knew it was worth the money so I purchased the 600 gram scale too.They also work great for weighing my small packages and envelopes that I mail,now I can figure my postage before going to the post office. They are both very easy to use and I'm very satisfied with the quality of both of these scales.I recommend these two scales to anyone needing a small scale. And for the price,I am glad that I bought both of them. Good Luck

Worth the low price, but not very durable.
This little scale is accurate and very handy. I think, if dropped, it would be done for, however. I tested it with some test weights that I have. Read more
