    Great fitness tracker

    I was deliberating between a few different fitness trackers, and the Fitbit won out with the versatility and discreet look. After a few weeks of using it, what really shines in the alarm. I'm someone who can sleep through 10 alarms in the morning, and this vibrates your wrist and wakes you up silently. I'd buy this just for the silent alarm!

    Have been using the Fitbit for about a month and thoroughly enjoy all the data it tracks. The Email summaries that I receive are most helpful and keep me on track for my fitness goals

    Really like the way it feels. It's light weight and works great. The thing I'm not liking is it doesn't stay charged long

    I purchased this item for my girlfriend and she loves it! We both have on (I have the charge) and we like to get into contests to see who can walk the most steps throughout the day.

    For the money it is a better value than its competition around the same price range. I looked at all of them and this was the best.

    I had been debating to get the flex or the UP from Jawbone. I chose this one is it looks nicer and price is better. It very easy to set up and fun to see how much you walk. I really like how it can track my sleep pattern also. I had linked it to My fitness pal & Map my run so that it syncs to fitbit and keep track of how many calories I took in & burn. There are a couple apps you can link to. Great devise and I also got my husband into getting one too.

    The Fitbit Flex is a capable fitness model. Tracks movements by day and sleep by night. It is hard to fool. Sleep tracking is questionable. Overall a decent product. Would recommend.

    I love my Fitbit Flex. It keeps track of my steps and helps me stay aware of what I'm eating. I can log my meals and it keeps track of your daily calories in and shows what you burn.

    I purchased FitBit Flexes for my entire family of 4 and they absolutely love them! Super easy to setup via smartphone and you can track your progress via the FitBit app or using the USB device they give you. Add friends and family on the FitBit app and compete! I particularly like the fact you can sync the FitBit app with MyFitnessPal. Overall, I am very happy with the purchase and would recommend it to other!

    The fitbit flex has helped me monitor my level of calories burned to calories consumed. Unlike phone apps, the fitbit flex automatically monitors my exertion rates, shows how far I traveled, if I did vigorous exercise, if I slept well and how long. At the end of the day, I look at my fitbit dash board and see if I need to exercise more, and how many more calories I can eat and stay in my target range. Its makes my weight loss simple and streamlined.

    I had my fit bit for two weeks before it stopped holding a charge. I contacted customer service and they replied quickly and replaced it without any issues. Other than that great product and it's easy to use and works well. Good tool to give you a good idea of how many calories you burn in a day to aide in your weight loss and fitness goals.
