After fitbit was sitting for a couple months, I went to recharge it and found that it wasn't working at all. I contacted the company because I hadn't had the fitibit long enough or used it long enough for it to short circuit. Inititaly they said they couldn't help and that fitbits don't last forever. I'm aware of this, but think it should last longer than just 2-3 months of use. They then offered me a discount on my next purchase, but I really am not interested in a device that costs a lot for working a little. When the fitbit worked, it was great.
