    The FitBit is great! Needs a clock on it. The product does do everything from tracking your steps and water intake. The FitBit also tracks your sleep as well.

    I love my Fitbit Flex! I have basically earn it nonstop (except for a few charge breaks) since I bought it a month ago. I have more energy from getting more exercise and I've lost about 7 pounds. I just completed my first challenge with some Fitbit friends and that motivated me even more. I would feel lost without it on!

    Got this to compare against the Jawbone UP band and have gotten spoil with wireless sync. Once I added my stride lengths it gives better accuracy on how my steps I have taken. Integrates with myfittnesspal and iCardio app I use on my phone. Would buy again if lost.

    I got this for my wife for her birthday and she loves it. She hasn't taken it off for a month. It tracks her activity level and helps motivate her to reach her daily goals. Her favorite feature is that it tracks her sleeping and let's her know how many times she woke up and how restless she was. The product is a little pricey, but performs well.

    Gift for my boyfriend so he could join the FitBit community. He wears a watch normally, so he needed something that would be small and discreet but that he wouldn't forget. This item has worked out perfectly. Tracks what he needs, incites a little competition between the two of us, and overall does exactly as advertised.

    Gave this to my wife, she likes it a lot. Does what you need for most tracking except no heart rate monitor. Tracking sleep option is great except you have to tap it a bunch of times to go into that mode and sometimes you don't know if it's in the mode or not....

    I like that the lights show me how active i've been,but i wish i could see the # of steps i've taken like with the other fitbit. It is nice that i can wear it in the shower. I also like wearing it around my wrist so it's harder to misplace like my previous fitbit.
