    This is a great product. The bluetooth sync works great but it would be better if It didn't need wifi to do it.

    I was really looking forward to the wrist band. However, after wearing it for a while, I realized that it was just a little too bulky for me and that I wouldn't wear it all of the time. I traded it for the Fitbit One. I just clip it to my bra and forget about it. I am happy with my decision.

    Very easy to use, comfortable to wear but had to return it because it would not stay synced to my smart phone. Am very disappointed in that because it was a very good motivator and with viewing on a phone app, it kept me challenged!
