If one imagines it, will appear after a few seconds the result - they must not be separately switched on or off. As a power supply used 4 regular AAA batteries, which are easy to get (how long this hold, I can not say). The surface of the scale is made up of a continuous surface so that it is easy to clean. The processing makes a good impression.
