I got one of those FitBit... I think it is called Flex, it is the one that you wear on your wrist. It is a pretty fun and cool little gadget. I just feel kinda bad some days because it shows how inactive I have been.
The only issue I seem to be having w/mine is the band is starting to come apart. This may or may not be normal. I bought another band off Amazon for like $5. I am waiting til this original band gets worse before I start using the new one.
