    I like my fitbit but it does seem to not count every step/milage as I know how far I walk and it is shorter on my fitbit, but I still use it and if at the end of the day I am short of my goal will go out and walk a little more

    The Fitbit Flex is a good device if you are mostly running or walking. My city recently began a bike share program and trying to tell the fitbit that you are out for a ride takes longer than the ride. It's just not worth it. I still like the Flex but wishing I had splurged for a Charge HR.

    It's amazing how these devices have inspired and motivation a generation the get moving. I own a Fitbit Charge and this Flex was given as a gift to my spouse. When coupled with the app, provides all the same functionality as the Charge but with the added benefit of interchangeable bands.

    I really enjoy using this product. It is easy to use and syncs easily to the app on my Iphone. I love being able to see how I slept at night. I enjoy using it so much that we bought my husband one as well and now we compete to see who gets more steps in a day.

    the fit bit kept me moving, but now i've gifted it to a friend. it's good to get/stay on track and form habits, but i lost interest in it all once i hit my goals--there weren't enough features to keep me interested long term.

    I purchased this for my 63 y/I mother. It was easy to set up and explain to her. She is able to log her food intake, steps, monitor her sleep, etc w/I much help or guidance. She loves it!

    The FITBIT is great. With the display screen you always have your updated info on your wrist. Love that it tracks steps, floors, miles, active minutes, sleep and you have a clock so no watch is needed. No downloading is needed. The Fitbit also has Wi-Fi which is nice at home to update to your home pc.

    As far as the activity tracker, it works good. I actually purchased this for my deep sleeping son who doesn't wake to alarms. I was hoping the vibration alarm would wake him. It only woke him on one occasion. I guess I need to find an electric shock alarm, maybe that would do the trick.

    Works well for a fitness trainer.

    Works well as a basic fitness trainer. Next step up has a few more bells and whistles (like heart rate), but if all you want is something to track steps and provide motivation, this will work. Make sure you download the Bluetooth app on your phone as well. Makes it much more convenient.
