Design top, flop function

Whoever seeks a balance here that displays an accurate result, will be disappointed. After 3x in succession repeatedly got a different result, I banished the good-looking piece of glass for a few days and gave her time to get used to their surroundings. But did not help, she was wavering in its measurement results. That the ground can influence the result, although it is well known, but in this make PVC or flow equal to 2 and 4 kg difference.
Since I wanted but not as fast turn on a few extra pounds, I did not give up and thought I try it once with the programming that was so touted as wonderful. It turned to me but again the next frustration one. The Clicking is annoying and when it came to the size, I had to convert first. Here namely with foot (American Way) is working and not in meters or centimeters. So after my age, height and my physical activity (assessment whether active, less active) typed, I tried my luck again. However, with even more consistent success. The weight is still wrong and the specified body fat percentage more to the perceived value of the doctor also decreases.
In the directions, is that moisture can affect the outcome, but the feet had to be moistened, if no measurement came about. This happens even with low cornea on the feet.
Conclusion of the whole: it is a balance that does not belong to the bathroom because it is difficult for her to deal with moisture. Their design is great, but just as great, the feet must be, otherwise the measurement is not working. And who has no problem with bringing a few more kilos on the scales, they might be used (unlike me) like to.
