Hello I bought this product based on the advice and comments. actually, this scale and very design makes a true quality, the accuracy of the balance, but on limpédance, it is out games, in fact, I read the instructions completely, I took all the settings, j have done all that I was asked, even wet the feet, and she sobstine to announce a 26% fat Grrrrrr ....... I'm far away, I think to be between 15% and 13% Indeed the last measurement made by a professional 17% it had announced two years ago that, since I still lost 4 kilos, and I took a lot of muscle mass by increasing my gym sessions. The limpédance measures are not accurate at all, except that of the weight, and I want to add, for a scale that is not that bad, hence the three stars. Now if someone could mindiquer if there is a trick to make it work or set up, let me know! Robert
