I bought this scale for medical reasons, so the related with my mother through the water in the body weight changes should be recorded several times a day. My claim was: You should go precisely as possible.
When my wife and I used the scale as a test, we were a surprise to, that we should have taken virtually in a few minutes of our own calibrated scales coming to these Soehnle scales almost three kilos. A return control with two liters Maßbechern full of water (= 2 kilos) disclosure, however, that here already missing 400 grams of weight.
It may of course be that we caught a so-called product Monday, which also speaks to the company, since the final quality has failed.
Conclusion: Good name but poor product. The purchase is not recommended as long as until the company sold calibrated products.
