I've been using this scale for several weeks and I regrettably can only say it is marginally OK and there are certainly much better scales out there. The scale itself seems decent. I have compared my weight on this scale to my weight on other trusted scales and it is accurate enough. I haven't seen any of the fluctuations seen by other reviewers.The body fat measurer is not reliable. I've seen my body fat numbers jump by almost 4% in a single day, which is obviously not physically possible. I would have to estimate the accuracy at +/-3%, so it's really only useful for seeing long term trends, maybe.The build quality is low. In the first week the start button became stubborn and I had to jiggle it to get the thing to work, but since then it has been OK. The buttons definitely have a cheap feel to them.
