    I love the data this tracks and records. It's super fun having the challenges with your friends because it motivates you to get moving. My only 2 complaints are 1) the wrist band is hard to snap in often and 2) it doesn't always sync with the app on my iphone.

    The tracker is good. However, my tracker and iPad, iPhone & in the gym do you not read the same amount of steps. I have tried different machines but to no avail, they are not even close in the readings that bothers me because I am not sure which is right

    Great and simple tool to track your steps, miles, and sleep quality. Good color bracelets and sizes to choose from. Almost perfect smart phone app to sync and track your data. My less favorite parts are the exaggerated displayed calorie count and the not-very-reliable charger for the tracker. All in all pretty much unbeatable for the money.

    Its ok...what I mean is after the newness wears off it basically a wristband. You have to look on computer to read it. I did like how it helped you attain a goal. This aqua color shows dirt and grim. I find my wife not wearing it anymore. Moral: Save your money

    I loved this tracker. I had had a garmin that wasn't as accurate as this one was. The sleep tracker was spot on and I loved the sleek band. Unfortunately the fastener on the band was awful and after having it ONE week I lost it. It fell off my wrist when I was out and because it's so light I never felt it. I couldn't justify spending another $100 on another one so I'm back using the garmin :( it's a great product. They just need to improve the fastener.

    My girlfriend made this purchase after a friend of hers bought one, and she was not disappointed. It does everything she wanted it to do and more. She like it so much that she went out and found a set of different color wristbands so it matches her outfit for the day.

    I bought this Fitbit to replace an UP band that had stopped working properly and was out of warranty. Where the Up was a bit 'clunky', this was much better fitting and was less 'in the way' during activities. The instructions to set it up and start using it were very easy and straight forward. One small downside, and it is very minor. It is labelled as waterproof, and for the most part, it is. However, unless you are wearing the band tightly on your wrist, it will get a little moisture inside where the monitor sits. Easily solved by taking the monitor out, and using a Q-tip to dry out the moisture.

    ok activity tracker, it counts steps and has a watch function and notifications. Too bad it needs to be charged frequently, almost as frequent as my smart phone. It also needs to removed for showering.

    it's good for tracing your steps and tracking your sleep. I wish it had a heart rate measurement especially while working out. The accuracy could be more precise.

    I love my fitbit. I'm a visual person so it tends to keep me on track and keeps me going. I just wish the battery lasted a little longer and vibrated or flashed on the device when it is getting low.

    Helps keep movement top of mind

    Overall I think it's wonderful for what I wanted -- something that would help me keep movement (not being idle) top of mind. It's motivational to have a goal and keep striving for it each day. It seems to undercount steps, but I'm ok with that because it just helps me shoot for even more movement. It doesn't register some activities. I do a body pump class and it doesn't register it as much activity -- sit ups, planks, push ups, weight lifting. But it does let you enter activity manually -- just doesn't count towards the step goal. It's also really interesting to see how restful or restless my sleep was. Bottom line - I love it!
