The luggage scale weighs with sufficient accuracy. But to cover the 3 button cell slips easily out to the effect that the coin-cell wegsprigen because they are under spring pressure. My advice: cover with a clear adhesive tape fix. The other defect is that the built-in LED lamp responds to very light touch of a button. This button is not sunk or otherwise protected, but exposed. If you are not careful, the scale light up unnoticed in the trunk, because anything presses the button. And this can easily happen. This leads to dead batteries. Ever me the additional lighting function is suspect. I want to weigh and not light. This is marketing without meaningful added benefits.
