A device that is simple to use despite its many functions. You can learn all about the composition of our body weight but also of course the fat percentage, water, bone mass .. In short a lot of more or less interesting stuff, but as they say "who can do more can do less" One can also just know his weight. This is a good product and the announced figures are stable, ie if you weigh yourself out of curiosity 2 times, and what will be essentially the same values that will then appear possible to cheat by choosing the weak when it suits us :-)
