After the particularly good reviews we chose this product, an error: The scale weighs so imprecise, so they showed after repeated weighing of a difference of more than 1.5 kg. Actually, the scale EVERY indicated otherwise. Particularly if before a serious man weighed, the next weight automatically was higher. Even if one example is. weighed a kilogram package, the balance is not indicated plus 1kg, but plus 1.4 kg. The equipment will be returned promptly today. The criticism in the reviews difficult Battery insert I can not confirm, however, that worked perfectly.
