I had previously had a scale that auswertete also the body fat and the was now in handling very complicated. In contrast to this it was necessary for the Söhnlewaage tap Activate and depending on the location, the results varied greatly, this has never happened in the Soehnle scale; one imagines it and get a result no matter what the location and the scale does not turn on when any small Shake a! I'm super happy with this purchase and grateful for the great reviews about this product from Amazon!
