Nice features when it works, but just had a third device fail
When it works, it's great. Unfortunately after about a year (right around when the batteries fail) is when the problems start. After changing the batteries, it has trouble reconnecting to the wi-fi, goes into endless loops, turns on when nobody is around until the batteries are drained, and basically doesn't work. I'm on my third device now. After the first failed, FitBit refused to replace it. After the second failed, they send me a replacement. It failed in almost the exact same manner. And it seems to happen after a year, after which it is no longer covered under warranty.
