    Love how it tracks my steps as well as my sleep. And best of all is that it syncs with My Fitness Pal. Another plus is that I can change the band so that it coordinates with my clothes each day.

    The Fitbit works great for all the functions. It is sensitive enough to be realistic but not too sensitive to monitor sleep patterns.

    Product is awesome. I wish the premium services were free though. Keeps track of steps, I can easily see how Im doing by tapping the band. Sleep function is super, it helps my doctor and me figure out how to improve my sleep quality. Alarms are helpful for waking up and as a reminder to get up and move around.

    I love my fitbit. It challenges me to walk my goal of 10,000 steps per day. And, I have it synced with myfitnesspal where I log my food for the day. Overall, I am super pleased with this product.

    Love my fitbit! This has been a great way to challenge other family members and as a group try to be more aware of our amount of activity each day. The sleep tracker is really helpful as well.

    I wear my FitBit Flex everyday to track my steps and try to be a healthier human being. Working at a desk job makes it hard to get extra steps, but the Fitbit makes tracking my steps super easy.

    This works pretty good so far. I like the ability to accurately count steps and how it syncs to your phone. It also tracks sleep patterns and you can enter in the food you eat to help track calories.

    Very happy I got the FitBit Flex. It is really helping with my weight loss and making sure I get up and move. The vibration for my alarm is also much more soothing than a regular alarm clock!

    I got this after I saw a friend wearing a similar device and after doing my research, decided this was just what I needed to help with my new fitness plan. It even monitors your sleep which is a big plus for me since I've been diagnosed with sleep apnea. It also syncs perfectly with My Fitness Pal app which I use to help monitor my calories and now here I am... 30 lbs lighter in just 4 months. It won't lose the weight for you but I love this product and highly recommend it.

    I tried for months to find this in Houston and it was never available. Found it at Best Buy in Omaha. I love it. It syncs with my food tracker that I was already use to, so I did not need to learn a new food program. However you can use the fitbit food tracker if you prefer. It monitors steps, activity , sleep, etc. Allows you to set your own goals, which is nice. I even can use it for my alarm. I love the fitbit flex. Now to get more colors for the band. that would be nice.

    The flex feels very comfortable on my wrist, and it's very easy to use on my iPhone. It also looks nice and it's easy to wear it with anything. Its battery lasts about 5 days (with auto sync off). The only drawback is the price, I cannot justify it's $50 more when compared to the the Misfit Flash or the iHealth, but it certainly is a nice fitness tracker.

    The FitBit Flex is a good fitness tracker that really motivates me to move. It is very interesting to look at you sleep tracking history charts. Sometimes, when I am riding a scooter or simply clapping my hand, the device goes into sleep mode, but that is not a big problem. It is great how the tracker electronics can be removed from the band because I seems it won't last that long. Having this device for a few months, I am already noticing some scratches on the band. Good thing that I have Geek Squad Accidental Protection!

    This was a great purchase to track how active I am. The unit is easy to set up and use. I didn't need all the bells and whistles of the more advanced units, so this was a match for my needs.

    Great Pedometer Feature

    Fantastic for keeping up with steps and miles walked/ran during the day. Many more features that I have not tried yet but plan to use in the future. Bought primarily to track how far I walk and/or run each day. Daily results provide incentive to maintain or improve on goals initially set. Unlike typical pedometers that attach to your belt and show your results on the pedometer, the Fitbit Flex requires monitoring your results either by smart phone or on your computer.
