First a good thing to know: you can use this scale "normally", ie without WiFi internet connection and the software, which is not very clear in the descriptions. You step on the scale, it lights alone, and legibly displayed on a light weight dial. If you stay a few more seconds you also have a body fat measurement that appears. There. Effective and precise enough in terms of weight, and reproducible, which is not so common. If you weigh item multiple times, you get the same weight. Phew.
In terms of software, the setting is a bit unusual but if you follow the instructions instead of trying alone, it will be fine. Obviously it is necessary that your bathroom is not too far from the "box" Internet. Initially I thought I am not used the software, but ultimately it's not so bad to take its weight and the overall trend over several days or weeks what is more interesting than the weigh daily.

I walk around 90-92kg me, and my wife 58-60, so the values ​​that the scale makes the distinction. No luck, my big son is in 85kg ... so I often recovers unidentified measures will neither on the weight curve, not on mine. A little annoying. For the rest, I'm a bit skeptical about the extent of fat ranging from 2kg a day ...
