mainly because it has shown the weight more like a random system. I bought it because I liked the design, the price is very cheap, the additional radio Tinen I have in accordance with the principle of "if I do not need them, they hurt not" considered. Regarding these functions, I've missed in the operating instructions, to which reference values they are based. Such values may be only in the form of domains, there is for example no "ideal weight" for all people of one sex and age class. People with a very low fat content can be very athletic, but also very sick. How exactly these values are measured, my knowledge eludes, IMHO, the only interesting if you're professional athletes or has health problems. Or both, which is not indeed so rare. Then you will however need a professional measurement. Well, I've just tried and when entering the data found to have the same always, both the key for the reduction of value as well as those for the increase led to an increase. If I can ignore, because almost only the body mass (falsely: the weight) I was interested. I have in the bathroom for half an hour repeated measurements performed eaten nothing in between, drunk, made nothing, and the readings were more randomly oriented. In a narrow range indeed, but that's also not what you would expect from a balance. Therefore: back to Amazon, settlement as always 5 star mature. Meanwhile, I have the Soehnle Silver Sense, which is fully ok
