    My daughter bought this for my wife. Although the item works perfectly, the app is a bit complex for her. To be fair, I have to say that my wife is a bit technologically "challenged" (lol).

    We bought this as a gift for someone looking to get in better shape. It looks great, works great (especially with Apple compatibility), and does the job. If someone is starting to become more health conscience, the FitBit is a great tool to track activity.

    Overall I really love the Fitbit. It is mostly pretty accurate, measures calories burned and overall movement as well as excersise. I am very happy with this product.

    Love that I can put it on and not think about it. Simple taps and I know my caloric status. All my info is easily accessible from my phone and works with MyFitnessPal.

    It's still new, but I am amazed at the information and data output for daily energy output, steps, calories, sleep etc. Very easy to wear and use on a daily basis.

    Best activity tracker available

    The flex is very easy to set up and start using. It holds a charge for almost a week. I love the silent vibrating alarms and use that feature a lot. The sleep tracking (however depressing it is) shows how much sleep you get, how many times you are restless and how many times you wake up. It's easy to set and track activity goals. The display is VERY minimalistic with the five LED's that show progress when you tap the band. I've had it for about 6 weeks and love it.

    Works well after getting used to putting it in sleep mode. Confusing at first. It takes a series of rapid, light taps with a fingertip. The same to signal that you are awake in the morning

    Overall, a nice device. I prefer the features of the clip on, ability to read steps etc at the push of a button, but after its clip failed on day 3 and I lost the device i bought this one. The charging clip is a hassle, very susceptible to any contamination. Every time I charge, I have problems. I do like the interface and program as well as weekly updated summary

    I bought my fitbit to start a new path towards my health. Three of my coworkers have fitbits as well. I love it! It gave me a means to first find my daily starting steps and to set gradual realistic goals. It's been a great tool for me and I love it's functionality. I use the app which I sync to Loseit! And together they have helped me lose 7 pounds, feel lighter on my feet and just feel better. This is just the beginning of my journey with my fitbit!

    Bought this as a birthday gift for my girlfriend and she loves it. Only issue is getting it to track steps properly on a treadmill, but putting it around her ankle has fixed that problem.

    Bought this for my boyfriends mom and she loves it! She wears it all the time, only problem that she had was that she isn't very great with technology so some of it was a little tricky but we were able to help her and show her what she was/wasn't doing.

    Purchased for wife, it is very easy to use n works great with her I phone. She likes finding out how many steps she makes in a day, also she can track her calorie intake for the day with the phone app. The app is just as important as the device, it's lite on her wrist, not binding, color can be changed, only thing that could be improved is time in between charges, other than that it's great.

    This product works well for basic fitness tracking. If you are an avid athlete or looking to do more advanced tracking I recommend spending the money to get a little higher end tracker.

    I received the fitbit for my Birthday. It works well, I have had no problems with it. However I was hoping for more, it does not link to my phone. I have a windows phone. All and All I like it.

    Great value for calorie counting!

    The flex does exactly what it details. It counts your steps that are accurate, calculates calories burned based on step count. You can track food calorie intake, water intake as well as sleep patterns. The vibrating alarm is a great feature. The phone app is great to use and you can sync several times a day. You can also have a friendly competition with friends and have step challenges. I enjoy the flex and wish the supply was better so more friends could enjoy the benefits as well.

    Liked it for the 6 days I owned it. It fell off my wrist while out shopping and I was unable to find it. Very comfortable and motivated me to get off the couch. I would purchase again.
