Intriguingly compact and low cost scale, but problematic
I purchased several of these scales for use in an educational physics lab. Their compact size, low cost, and relatively high capacity for a 0.01 g resolution seemed to good to be true. Looks like it was. The auto-off feature is extremely annoying. It turns off in only about 30 seconds even with activity (although it claims it only turns off with inactivity, just not true), and when you turn it back on, it auto-tares to 0! That's right, it turns off constantly and then doesn't remember the reading before you turned it off! Also, at least one of the 22 scales I bought behaves very strangely. A lot of the time when you press the tare button, the reading oscillates wildly, and will eventually stop at some non-zero number. After multiple tries, it will zero properly. It was about a fourth of the price of the next cheapest acceptable scale, but I guess you get what you pay for.
