    I loved this when i had first gotten it and when it was becoming popular just left it on and went about my day and exercises although the band would pop off too easily as its one of those pop in ones so you do have to make sure ur not gonna do anything where it pops off. But the battery life on it was A1 and it did its duty pretty good i would work in the fish department and my wrist was always dipping in water grease slime and guts and its alwayss survived and still works till this day. Its great for something cheap and to calculate or keep track of ur day steps ect.

    Whether you're close to your weight loss goal or far from it, the Flex is an excellent device that counts your steps, calculates your burned calories and more. The Flex stands above its competition when it comes to accuracy

    I LOVE my fitbit! This was actually a replacement purchase ( Get the 2 yr BB replacement plan for 14.99 ~ SO worth it) Overall I have had a fitbit since Dec 2013 and I LOVE it. In the first 13 months I lost 45 pounds and being able to track my actual calories burned using my Fitbit was a BIG part of that. You can use the Fitbit app to track your calories too, or you can do like I did and link your Fitbit to another app such as MyFitnessPal. Either way the key to success is the simple math of fewer calories in than out, and this device can help you with that in a big way!!!

    This was for my 10 year old grandson who has started doing kiddie triathlons with his dad this year. He set up the Fitbit by himself on the computer (it was that easy) and created his own account to track his steps and food intake. Pretty simple process and got him more involved in being healthy.

    I really like this activity tracker. The app helps you keep track of calories in and out. I also like the sleep tracker. The one thing I don't like is the band. It is hard to put on so I had to purchase another band.

    Feedback for steps, calories and sleep all work together to keep you on track on a daily basis. All days are not the most successful but looking over a week and seeing the averages shows that progress can still be made.

    Love my fitbit! Easy to use and sync at any time using my phone. The sleep feature is pretty cool too, it tracks how long you slept and how many time you awake or are restless per night. Also love the social feature which allows you to compete and track the progress of your friends who also have fitbits. Only downside is that the fitbit flex does not track flights of stairs climbed like older models. Overall great product!

    I bought this as a gift for my brother and he loves it. After seeing how well it worked it made me want one too. My favorite feature is the sleep tracker and its pretty accurate too. I'm in and out of sleep all night, and it picks up on that and tells me how much sleep I actually got.

    I love this because it keeps me accountable for my goals and health. Love that it tracks calories and adjusts to how many you need compared to ones you burned. No heart rate monitor but I have a polar that does that.

    Fitbit Flex was a gift for my granddaughter (12 years old). I helped her change the band (from the large to the small, which was pretty easy). I also helped set it up, although she could set it up by herself. She loves it!

    Because of the Fitbit I try to be careful about what I eat and drink. My daughter challenges me to keep up with my walking too. I love the fact that the fit bit tracks my sleeping pattern. I am aware that I am a restless sleeper at times. But didn't know how many times I actually was restless.

    I bought this for my husband. he plays tennis everyday, but working on the road most of the time. he fixes machines, so he is always getting greasy. i bought this one so we could change out the band if it got too gross, also because he could wash it. he loves it!! it makes him walk and move!!

    The fitbit was a Christmas present that I didn't know I wanted. It's a great tool to get yourself moving but what I like the most is that it tracks your sleep. The dashboard provides a lot of good information. If you take the time to input your meals & snacks it would be great for weight loss.

    I have to admit when I bought the Fit bIt Flex it was at my sons request. He wanted me to join in the challenges . I figured I would use it once and that would be it. But challenging yourself and others becomes addictive

    I received my first Fitbit Flex as a gift and immediately began using it! It is easy to use and it does challenge me be even more active than before I started using it! This was a replacement because I lost the first one after three months. I highly recommend buying s strap that has a buckle! The French Bull makes some cute ones! They are available at Best Buy!

    This was on sale at the time of purchase, so I jumped on purchasing it. It was easy to set up with with iOS device and the Bluetooth works great. The bands wear out quickly which is why I picked up another pack to have backups.

    I bought this for my mom, but I already had one. If you want to stay motivated, then you should buy one. I always wear mine. I am actually going to upgrade to the charge. Being able to challenge friends is the best!

    My daughter loves her Fitbit flex. It's very easy to use and syncs easily with her iPhone so she can monitor her progress. The app is user friendly and the device isn't complicated at all. I love the flexible band and the multiple options that they offer. All around a great purchase.
