    Fun and easy to use.... Occasional problems syncing but overall very user friendly. Can do as much or as little with it as you like.

    The Fitbit Flex is great to get motivated to MOVE! You can compete with your friends with your weekly steps! It also tracks your sleep patterns. You can use it as a weight loss tool, too.

    I bought this for my wife for Valentine's Day. She is on a weight loss/fitness kick and I thought this might be a fun little device to try and use to help track her progress. I didn't expect a lot because my wife isn't into gadgets the way I am and when I get her one she usually seems indifferent to it. However, once she set it up and tried it out, she immediately told me how cool it was and how it was a nice compliment to her Weight Watchers regiment. She got me on this weight loss kick too and I got the Force that has the led display like a watch. The flex has a series of dots that light up to tell you your progress. You need to check on the computer or your mobile device to see the specifics of how you are doing. The force display allows you to check on the fly without logging into your computer or mobile device. I also think it makes a nifty watch. Overall though, the flex does what it promises and my wife likes it, so it's a solid 4/5 stars.

    Long battery, but can be off on step tracking. The companion app is great, but should include integration with Apples health app

    Even the large band is sometimes too small. I think I prefer the fitbit one that I can just stick in my pocket or clip on a shirt.

    Love my Fitbit Flex - also bought the Aria scale at the same time to track my fitness. Very accurate, though when mowing my yard, it tends to overestimate my steps due to the vibration of the mower. It's nice to set a step goal and reach it, and I love to see how I've slept each night. My only complaint is that when it needs recharging, I lose data that might either add up to my activity for the day or I have to miss a night of sleep tracking while it charges.

    The entry-level Fitbit is okay for what it is - an expensive pedometer. It's highly sensitive and I routinely gain an extra 400+ steps on the bus ride home from work. But, as long as you adjust your goals, this is fine. I've had to replace it once in the last year when it stopped charging and syncing with the iPhone app. But, Best Buy replaced it quickly, no questions asked. All in all, it's a good purchase!

    I have a couple of different fit bits and use this one all the time. I love that I don't have to clip it onto clothing (have one like this to and inevitably I'd forget to put it on) and it seems to be fairly durable. The down fall is the battery life. It pretty much sucks. You will have to recharge this little guy at the very minimum, every 6 days. The little window where you tap to acknowledge sleep is very hard to work. I have to tap extremely hard and many times to log sleep hours. Overall, it's was a great buy.

    I have been using my fitbit flex ever since I purchased it about a month ago. Overall, I really enjoy using it to challenge myself to walk more every day and meet my goal. The only downside is that it tends to update or "lock up" a lot. The lights dance around so you can't tell how close you are to reaching your daily goal. You either have to plug it into the charger or reset it. However, all the information remains unaffected. I would recommend it, though I've never tried any other model or brand.
