    This is something I would highly recommend getting. It's easy to use and you can track your steps and your sleep along with the food you eat and your weight. It easily integrates with other apps like Myfitnesspal and pact. Would buy another!

    This is a good device for step tracking and competing with friends in amount of steps. You have the option to log food like on my fitness pal but this particular fit bit doesn't automatically track your sleep. And is not compatible with Nike run+ or any other running app

    I love this fitbit flex tracker. It keeps me on track and allows me to set fitness goals. The only concern is the closure on the band. I lost it 3 weeks after purchasing it. I didn't realize it had fallen off until it was too late. I have a new one with a different band.

    I have loved not only this product but the app as well. The more I get into tracking my steps and fitness, I wish I could do more and actually see the results versus just lights....hearing great things about FitBits new bands so about to trade up and check one of them out!

    I read all of the reviews on different kinds of activity trackers. The fit bit seemed to be all I needed, and in my price range. It is small enough to not be bulky, and it did everything it said it could. The app with it is nice too. I do wish it could track bicycling.

    It isn't worth the money without my fitness pal.. But is wonderfully accurate. I really want to see it be more than just a pedometer though. If I could track my heart rate as well as calories burned/distance on a specific jog around the block, it would be the greatest thing ever.

    Once I figured out how to use it, it's great. Tracks calories burned, activity, sleep pattern, great silent alarm, easy to sync. Support was very prompt in addressing my concerns.

    Works great, counts my steps, tells me when I reached my goal, even motivates me to get more steps. The phone app lets you keep track of your calorie count, weight, body fat%. Pretty cool stuff if you like to have all your information on one website. The sleep tracking is also a great feature. Seems to be pretty accurate. Tells you the duration of your sleep, how long it took to fall asleep and a few other neat things. The only negative thing I have to say is the band gets bruised up here an there if you wear it 24/7. They could provide you with a extra. You can however purchase extras on their website for 15 dollars. I would recommend this product to friends.

    This is so accurate! I'm so happy I decided to purchase this. It keeps up with everything; number of steps, calories, active minutes, and sleeping pattern. It motivates me to get up and get my steps in. Do yourself a favor and get one!

    Steps seem accurate. Haven't used it in water though and don't really plan to. Does sometimes take a while to sync with my Galaxy Note 4 phone but otherwise the Fitbit app is great for keeping track of food, water, sleep, and challenging family and friends to keep everyone motivated and moving! After having it 2 months now I charge it every 6-7 days.

    After several weeks of research I decided that the Fitbit was going to be my choice. I already owned the Jawbone Up, but really wanted a secure bracelet. I was able to connect with my friend to keep each other motivated. I do wish it had better exercise tracking though.

    good product, makes you more aware of how much activity you are doing throughout the day. The only complaint I have is that it doesn't always count your steps if you are pushing a stroller or shopping cart/

    I love this item, I use it primarily to track my sleep quality. It allows you to see information about your sleep habits that you never could have had otherwise. The battery life is great (4-5 days) and it re-charges completely in about an hour, I highly recommend this product.
