    My fitbit is somewhat accurate, it can be tricked, but still requires you to move to do it. Good for insurance discounts if your company is going for fitness monitoring. The sleep tracker is interesting to see if you have trouble with your sleep.

    It is easy to set up; it only needs to be charged every 5 days; it still works after swimming and showering. Wish it would work with my Droid RAZR MAXX, but I still like it enough to keep it. I know others who returned theirs' because of this issue.

    Easier to keep track of intake than using pencil and paper!! Find my entries are much more accurate. Also find that I am pushing myself harder to make my "steps". Great tool for exercising and watching what you eat.

    When I first purchased the fitbit flex I was really excited to use it then two weeks into using the product it stopped working for 4days. The price is not really worth it but it does it's job. I don't like that it gets dirty so easily.

    I've purchased seven of the fitbit flex units for family and friends. I love the competition with friends and I've seen an increase in activity because of wearing the band. The fitbit app is good and connects with Myfitnesspal and other calorie counting apps. I've lost 25 lbs this year and the flex has been a part of my success!

    I bought this for my wife, and she really likes it. However, two issues; this is the second fit bit we purchased because the first one didn't work, so be aware to test it immediately, and secondly, it senses based on arm movement, so if you're walking, but not moving your arms, such as shopping at Costco, it can't count the steps. But otherwise, it's a good product.

    The Fitbit is simple to use, and increases motivation. Being able to tell at any time how active I've been has led to influence other decisions (should I take the dog on a long or short walk). And the sleep tracking has really helped me be aware of how much sleep I think I'm getting versus how much sleep I am actually getting.

    I really enjoy it. I like how it tracks sleep and steps. I was surprised by the records of sleep. I didn't know I was so restless.this helped me to change my routine, therefore improved. Also I get discount through my health insurance by downloading data.
