The scale meets great, what to do. The readings I consider credible ;-) Especially the "repetition reading", which showed quite times up to 1kg difference with my old scale proves that the scale is really equipped with good sensors / springs. Body fat, water and muscle percentage is doing but only measured when a user memory is used. The flat design I like very much and the scale means it fits in quite well in tight spaces or under one or the other box with feet. The only drawback for me is that I can not read the symbols to body fat, water and muscle percentage in normal lighting. If the order of the numbers you will remember of course that is fine, but with an illuminated display or a larger display that would naturally more beautiful and worth the full 5 stars. The matching application for the course Analysis I have not tried yet, but for me is not relevant for valuation. For the good price / performance ratio, this scale is definitely a buy recommendation.
