If you want something to remind you to be active then buy it. But it only works for running, walking and if your moving with your arms. If you want it to measuring biking or stair climber your out of luck. The worst $150 I have ever spent. A pedometer would be MUCH cheaper and do the same thing.
This was the worst $150 investment i have ever made. Im on my 3rd band now. I got it when they first came to market. The screws rust, if you try and change spacer after it getting wet a few times it will not lock back in. If your looking for something like this go to Jawbone.com and look at the up band. It does not have a LCD display but does more then Nikes Fuel Band
