    Okay product but not a wow 11/5/2014
    Steve from Santa Rosa, CA  

    Fitbit does a good job tracking my active minutes during the course of a workday. I am somewhat skeptical about its accuracy in counting the number of steps and calories burnt - I think it overestimates these. The feature to track sleep pattern sounds interesting but not that useful. It sort of reports the number of times you are restless, but not more (can't tell if you are sound asleep or just lying still, for instance)

    HELPFUL?: Yes No

    Great product 9/11/2014

    So far I have been very please with the fitbit. I read a lot of reviews previous to my purchase. I was a little hesitant based on some reviews but decided it was perfect for what I wanted. There may be better products out there but this is perfect for me. It's easy to use and wear. I love the sleep tracking and I love being able to track my water intake daily. It keeps me motivated to be more active which is exactly what I was looking for.

    HELPFUL?: Yes No

    Works great but.. 9/7/2014

    Only issue encountered is the fact that my iPad or iPhone will not discover the Fitbit in the Bluetooth mode. Couldn't find a fix for this issue.

    HELPFUL?: Yes No
