I am sorry but I have to say this is a bad product. I ordered 2 of them. One was deffective- I can understand it. Probably bad sensor - shows still 0.00g. Money refunded by aliexpress. But my main concern is about the working one. It needs really high voltage form batteries. Does not work with rechergeables - even fully fresh charged at 1.4V/cell. Needs like 1.45V or more. So even if you use alkalines you will get "Lo" even when the battery has like 85% of energy still inside!!! Really badly designed product! DONT BUY! When it shows "Lo" it shuts down and does not work. (And yes, the one with bad sensor does the same so it is not like I received differently deffective one.)
More precise than I expected. I made me a few weight stones and caliratet thrm at wörk, where I have access tu a very expensive laoratoy scale, ant the display told me exactly the same, not even one digit difference! Great!
