    My FitBit Flex works great. Keeps track of my activity, sleep and has a great alarm to wake me up in the mornings

    Love this product! Really helps you recognize how much (or little) movement you get in a day plus a daily goal to work towards! Not to mention it links nicely with my fitness pal (which I use to track my food intake)

    Overall, this is a great activity tracker that even picks up my movement while bicycling. It would be nice if there were more apps it were compatible with but I can't complain. It's supposed to sync as soon as I open the app, but when I log in on the computer, it doesn't always sync up right away. That can be frustrating. Definitely worth the money if you just want to be more aware of your activity.

    Cool little fitness tracker

    The Fitbit flex is a nice little fitness tracker that can also monitor your sleep patterns. It can estimate your calorie consumption and you can set goals: number of steps, calories etc. For me, the features I use most is to make sure that I do get some exercise throughout the day (walking, climbing stairs) since I have a desk job. Also, the alarm function is pretty useful. Now, if only Fitbit would allow us real-time access to the raw data stream, we could do wonders with this little guy.

    In a few years time this will seem quaint, but for now I think this is the best out there. It's still fundamentally a high-tech pedometer, but one that sync's to your phone. The sleep tracking feature is one exception, and while I'm not sure of the real value, it is something I find myself checking almost daily.

    I love the light weight and portability of the product. The app is user friendly. The only down fall is that it does not count weight bearing exerices for calories burned. But that can be added within the app.

    I've had my Fitbit for three weeks. So exciting to actually see activity throughout the day. Definitely motivated to move more. Three weeks in no longer syncing since 6/22 update. I've done all the troubleshooting multiple times and now the only time it works is if it's plugged in to power source.

    This is a wonderful product for tracking your activity with a great supportive community. It provides a healthy competetive atmosphere with options for finding new friends all over the world, as well as establishing your own competitions with friends that you know. The weakest feature is the clasp on the band. I suggest additional security bands or temporary tape between charges.

    I really love this product. It keeps me on track it counts all my steps without me having to remember to turn it off and on. The only thing I wish it did was count my sleep without me having to turn it off

    I bought this for my husband for his birthday and he Loves it! I got him the "entry level" Fitbit to be sure he would like it, and I wouldn't hesitate to purchase this or a higher level Fitbit in the future.

    Bought for my 13 yr old son and it is great for him. The silent alarm is great and it is a great way for him to make sure he's getting enough exercise.

    Purchased for wife. She really enjoys it to track her daily steps. Battery life is exceptional,and it doesn't appear to drain the battery life of her iPhone 5s as much with the Bluetooth usage. I give it four stars, because in my slight use of the product... The Fitbit app does not give you a more intuitive experience and feedback on your efforts...unlike the Lark app or others.

    Good Basic Device

    The FitBit Wristband device is a good quality basis device for tracking day to day level of activity and to a lesser extent sleep patterns. The internal battery will last only a week and then must be recharged weekly. The Bluetooth interface works very well with my Android phone. The device can track types of exercise, running, tennis etc. but it is not easy to program exactly what is being tracked. The band is a soft plastic and very easy to put on and remove.

    My wife wanted a Fitbit but felt the HR model of which I sport wasn't sleek enough her. Enter the Flex model and in a great slate color. She's hooked and uses at on a daily basis to hit her fitness goals.

    I wanted a way to count calories burned vs calories taken in and the product along with the fitbit app is a great way to do that. The sleep tracker is interesting and is accurate. The fitbit has lasted the most 6 days on a full charge for me on a not so active week. I would recommend this fitbit for anyone how wants to count the calories in a very accurate way and log your food and exercise.
