To me, the FitBit is a fancy pedometer. However, my husband got one and it changed his life....for a while. He's very much into tech gadgets so he really responded to it and was really into counting his steps and all. He has since gained back almost all the weight he had lost. It really comes down to consistency and, of course, individual preference. If money isn't an issue, it's worth a shot. If it is, I'm pretty sure a pedometer can accomplish almost the same thing. I hope you get some other responses too.
