Bests & Worsts Reviews from Amazon

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.
