Goods arrived undamaged. After unpacking the device is activated by removing the foil between the battery and the contacts. Unfortunately, the scale showed the first try only a "Reset" and did not work after several attempts. This was due to a dead battery. Of course one could now safely unplug star, would be wrong in my view. The battery is a penny - articles and I always spare at home. (What can manufacturer / supplier for it if the item is somewhere in a warehouse long) Since then, does the scale properly. Tolleranzmessungen of +/- 0.2 kg, normal and absolutely ok. For this price you get a great balance. Would I buy again and again.
