Expensive paperweight
Worked fine - for a while.  Now stuck in the dreaded Sensing, Step Off, Thinking, ERR loop.  FitBit support comes back with "we're sorry you're having trouble, but your device is out of warranty".  Search this before buying - this problem is happening to TONS of people and FitBit is doing nothing to support the issue.  I am DONE with FitBit hardware.
