You get what you pay for!  I bought this scale because it was the cheapest on the market... and it is!
Right off the bat, the buttons would get stuck and the scale would not turn on!  Blank screen.  To make matters worse I didn't get to see this until after the return window expired.  My bad.  So now I'm stuck with a scale that works as a paper weight... that's it.  Do yourself a favor, pay a few more dollars and get a scale that will at least turn on.
