Really good scales for the price. I'm surprised of the accuracy and options. Only thing missing would be digital output via USB, but it can be powered via USB (and it's not advertised to give digital output anyway). So, very good product. 5 Stars.
Relatively good scale. fast shipping. You need to calibrate after receiving. There is included calibration weight. However seems scale is rounding weights +-20mg to show clean values. If I place 50g weight it shows 50.000 or sometimes 49.999. Then I add 20mg paper it still shows the same value as if 20mg does not exists. So that is not ideal. If I weight some non-round value like 150mg and then add 50g calibration weight, then you can see true weight which varies by +-5mg or more.
