The personal settings for the measurement of body fat have not been easy, because the buttons to be pressed have not responded (with fingers dry and clean). I've almost given up, it has still works. The scale measures at me now a value of water / fat / muscle mass and bone share totaling 119%. These are then so can expect 19% measurement uncertainty and the balance also did not appear. Nevertheless, I keep it - to weighing every now and then that's enough.
