reading, 0.01g ok; loyalty is ok, very good precision, most weighing close to 0.01g, occasionally to nearly 0.02 g (weight checked with the thousandth) on / off button bit practice 48 hours delivery, perfect; stainless term for the weighing platform ready misleading (glass or resin) but not of steel, so overall very saisfait after 8 days of use, product to recommend
