    My Fitbit has made me more aware of my movement during my day. I love the size and light weight. I can still wear my watch and other jewelry with it.I tried several other brands and returned them after a day of having them.

    I didn't like the fact that when my arm perspired the perspiration collected inside where the Fitbit is stored. Now I wear the band looser with no issues. Very comfortable and love all the different colors the band comes in. I also don't like that it doesn't have the stairs count feature. Love everthing it tracks and very user friendly. This is my second one and don't want to be without it as it really helped me to loose a lot of weight. Love, love, love it!!!

    I originally bought this to track my sleeping pattern as I have sleep apnea. Works well for tracking sleep, exercise, etc. I like that it is waterproof, I can wear it to my water aerobics class to track my exercise.

    I got the FitBit because I spend too much of my day sitting and working on my computer. Keeping track of my steps every day--and my sleep patterns at night--is proving to be very helpful in reminding me to get off my butt!

    This band keeps the Fitbit unit dry while exercising. It’s also comfortable while sleeping. It’s easy to see when you’ve reached your daily step goal. I use it with my weight watchers app also!

    Easy to set up and use, comfortable to wear. The battery lasts a very long time, and the software makes it easy to partner with friends with the same fitness goals. Also very helpful for increasing water intake.

    When my wife first said she wanted to buy these I was sceptical, but I bought them and gave them a try and I could not bye happier. They are light weight and very accurate. I have now lost 20 lbs in 2 months using these.

    This tracker records your steps, calories burned & sleep. I use it with the app for iPhone which also allows you to record your food and water intake. It is a great product to help you create & enforce healthier habits.

    I wanted something to track my sleep and activity patterns. This was simple to setup, has great battery life, and excellent metrics which are easy to view online. I picked an extra USB wireless sync dongle to update my Flex while at work. The company does make new firmware available on occasion - I recommend seeking those out and updating the Flex to take advantage of the latest fixes and improvements.

    This device was great for tracking my steps after a previous pedometer bit the dust, and is relatively easy to setup and use, but it's not without short comings. Unlike the FitBit One, it doesn't track flights climbed, and the display gives very limited feedback for what your steps are without having an approved device for it to sync with and get a readout from; most Android devices cannot sync with it.

    My wife and I both use the fitbits daily and Ive gotten so used to wearing it that I dont even notice it. It really helps encourage us to get out for a walk around the neighborhood last thing at night so we can complete our steps goal. If you are starting out a weight lose program this will help motivate you to get some extra exercise (I work a desk job and did not realize how little I moved). It seems pretty accurate, even if Im pushing a stroller and my hand is on the handlebar, it seems to register the steps. If you are training for a distance run it moght be better to use a gps enabled device, but for general runs/walks this is pretty good. A downside is that we've tried some programs (like Insanity/P90X) and the device doesn't seem to recognize those motions as steps... so after a 30 min (intense) workout you appear to have barely moved. Love the alarm function and use it all the time! Doesn't wake my wife (esp if we get up at different times). It is also a lot less "jarring" to wake up to the buzzing on your wrist rather than an alarm clock. The sleep log itself is alright but Ive had some nights where I cant sleep and it shows I slept like a rock, and some nights vice versa. Overall Im really impressed with it for the price, functions, and design. The accuracy is also pretty good overall, but if you need something to track intense activity like a workout video or long distance runs, you might consider something with a heart rate monitor or GPS for improved accuracy.

    This is the best item for anyone that would like to track their calorie intake, steps taken, how many miles jogged and the application is free. Best purchase ever and I really recommend this item! Best one out there.

    Fitbit Flex is good. Wish they hadn't pulled the Fitbit Force because the extra features really were nice. Will by the next high end Fitbit when it comes out.
