Review on Accurate Fuzion Gram Scale 200g/0.01g - Jewelry Scales for Precision Weighing in Grams and Ounces - Digital Pocket Herb Scale with 6 Modes, Tare Function - Ideal for Herbs, Jewelry, and Small Items (Includes 50g Weight & Battery) by Rachael Taylor

Accuracy seems to decrease over time with single use. I found out by weighing things I had already weighed a few minutes ago. But if you disable it, you'll get the same results as originally. The only other issue was that the calibration weight was too difficult to remove from the holster. Almost impossible. Otherwise it seems to work. I wouldn't use it for important precision stuff, but general usage seems reasonable. I guess I'm being generous with my stars on this one, but it does what I need it to do pretty well. It was cheap and the surfaces are cooler than others.
