Processing and operation of this scale is ok. I bought extra for the exact measurement of the Wasserentkeimungszuätzen for WaterCan (for Camping -> 0.02g Entkeimungspulver Micro pour à canister). Unfortunately, it was not possible with this scale to weigh 0.02 g. Under the scales 0.35g unfortunately only 0,00g indicated. For those who are less sure exactly need a good product. For my specific application (which is why I bought the scale schließlicg) shame about's money.
