    I love my new Fitbit! Great way to keep up with your activity and sleep. The group competition encourages me to walk even more. I would recommend this item to anyone trying to lose weight or just want a healthier life style.

    Very easy to use even for a beginner. The only issue sometimes is sleep mode, turning it on or off can sometimes be tricky but I have only had it a few days.

    This is an awesome product. My wife and I both got one the same day and we have both lost weight since our purchase. Thus is a great buy for people looking to lose weight.

    Slightly difficult to switch to sleep mode, but you get the hang of it. Miss having the digital display of the fitbit force with the time and exact steps .

    This is the basic model but does all the things I need. It tracks steps, calories, weight, sleep and water intake. Nothing extra to make it complicated!

    I bought this because I wanted to start moving more. On the plus side, I am tracking what I am walking, how many hours I sleep and how often I do a certain number of steps. On the negative side, it says it is charged for 5 days but mine seems to run out sooner and I find the band is difficult for me to put on...I would prefer a regular watch style band. Overall, not a bad buy.

    Easy to use once you enter a calorie event or two; it becomes a bit addictive which is what you are looking for with exercise. Has a very nice connectivity for Friends which allows you to share meals, calorie counts etc.

    For the price of under 100$ this little guy is able to track my steps, I can log activities, calories and other fit things that help me be more active. Works amazing with the phone and gps to truly find distance traveled.

    My wife loves it since she can exchnage wristband color and small size. It does not count floors as the Charger one however it is very good device for the price.

    I had a FitBit Zip, which was fine until I wanted to wear it swimming. The FitBit Flex is waterproof enough to wear in the pool, shower, etc without ever having to remove it. I wish the display showed actual numbers rather than dots. The sleep tracker is neat too.

    I like that you can wear this easily, no clips to attach like other pedometers. I also like that is automatically uploads your information versus a separate plug. The battery lasts a long time - almost a week before it needs to be charged and it reminds you when it is getting low on battery. It keeps track of your sleep patterns.

    My husband and I both have the Fitbit Flex and love it. It becomes a competition of sorts on who takes the most steps or who is more active in the day. While his battery lasts almost all week, mine only seems to last a few days.

    Both my wife and I bought a FitBit to keep in better shape. We have had a lot of FUN with them competing on step counts and watching calories. Both of us have lost weight in the month and a half we've been using them!

    i like the flex if you havent had any of the other fitbit products first...i bought it to be able to compete against my friends and family in challenges. I had slready had the fitbit surge and lived it and was used to the hr monitoring and the flex of course doesn not do that...i bought an apple watch and felt like it didnt look right to wear both watches so i bout the flex...my only complaint is the the charge hr was to hug and the flex doesnt do enough...but all in all i have lots of fit bit products and recomend thrm to any one that is starting to get more active!!!

    Lost my first one. I use a rubber band to secure it because it comes lose. Like variety of band colors. Awaiting the new Surge for accuracy in crossfit training and watch strap. Suggest aria scale for easy weight tracking.

    The color is very bright, and makes a statement. Make sure the size fits you - it is important for the accuracy.
