    I previously had the Fitbit Zip. I like the way this one syncs as you are moving instead of having to wait. Also the sleep tracking is nice.

    Still using the Flex due to allergies of nickel/copper for the Charge models. Works very well for my needs and keeps track of my steps reliably.

    I bought a Fitbit and loved it so we decided to buy one for my mom. She loves it! It is small and tracks basic steps and so on. Perfect for her!

    I finally bought this product first hearing about the fitbit product a year ago. It is such an easy way to track your steps and as a bonus tracks your sleep as well. Super easy to use and you hardly know it is on your wrist. As a test, I tracked my sleep for a few days then gave it to my daughter who suffers from narcolepsy. It was amazing to see the difference in our sleep patterns.

    i purchased the fit bit on the advice of a friend,i chose the wrist band one as i tend to lose or break anything clipped to my belt. it is easy to use and just as easy to sign up on the website,it keeps track of steps,heart rate,calories burned and will even keep track of your sleep patterns. the wrist band can be a bit difficult to put on at first but remains secure once on.

    Simple, motivational accessory that has helped me bring out my competitiveness again by achieving my daily goals and tracking my friends' progress as well! It is also impressive how it can track your sleep pattern, and it stays charged for a long period of time. My only concern is that the clip may become loose and the band fall off as it has once when something hit my arm.

    Absolutely love this. Has helped me so much that others in my family have boughten one each for themselves. Pushes me to reach the goals I set and I have been able to increase my goals once I have reach them. This is easy to use, set up, and they even send you your weekly progress which makes you strive to meet your daily goals. Highly recommended product that is super accurate.

    i have had it for more than one month. It makes me want to walk more each month. I do not take it off and it looks good with everything. It also tracks my sleep so I show my husband each morning why I am so tired. It tracks how many times a night you wake up. I use an apple computer and it works with apple products. It is easy to use Best Buy was the only place to have it in stock.
