    Although I like the Fitbit I question the accuracy of it especially since I sit at a desk all day at work. But with that being said it does encourage me to get up and walk around more. I also have not figured out the sleep mode. I cannot seem to get it into sleep mode so I don't wear it at night.

    This is not worth the 100+$ that it sells for. It does not track activity well, even walking and frankly has a lot of manual entry for something that is billed as an electronic tracker.

    No, I would not recommend this to a friend
