    I purchased this as a gift for my mother on mother's day. She loves it! I didn't get her the Charge HR like I have because my mom is a moderate walker. This is perfect for her!

    Initially I was very interested in the fitbit flex. When I learned of its release date, I purchased the Nike fuelband. Initially I loved the Nike Fuelband, it had a sleek LED, would allow me to track my progress on the device and check it as often as I wanted without the need for any other gadgets or phones. The charge time held up for almost two weeks and installation of the software was excellent. Then Fitbit released the flex. The flex is much lighter, which is great because I forget it’s on my wrist due to its light plastic construction. However; the wristband just feels like a cheap housing for the actual “Brain” which you must remove from the wristband in order to charge it. The “Brain” also holds a charge for approximately 5 days, significantly less than the Nike Fuelband. Where Fitbit truly shines is in the software. With your IPhone or android, you can get a wealth of information including the option to track what you’ve eaten and how you’ve slept. There are also quite a few 3rd party apps that can use fitbit as well; which makes it very flexible. My only real complaint is If it wasn’t for the display (which is only represented by dots) it would be more intuitive to understand.

    The use of a FitBit has proven to be very motivational in achieving activity and weight loss goals. It syncs with weight loss program and family and friends via the smart phone.

    I have had my Flex for a month and it continues to be a good motivator to get moving. My friend got a JawboneUp24 at the same time so I have been able to get a good feel for the pros and cons of this tracker in comparison to its competition. If I were to do it again, I would probably spend the extra $50 and get the Jawbone, but the Flex is serving its purpose well. Pros: it is sleek looking and comfortable to wear and never feels like it is going to fall off; the progress bar on the band (it is really nice to be able to get an idea of your progress by tapping the band instead of relying solely on the app); it is easy to setup and the app is easy to use; sleep tracker seems pretty accurate. Cons: it does not have an idle alert (the jawbone alerts you if you have been inactive for a period of time); lack of user interaction (Jawbone sends messages throughout the day, encourages you to up your goals, etc.); does not count steps if pushing a cart/stroller (unless you attach it to your shoe); pretty inaccurate when doing aerobics or class-type workouts; app does not have a barcode scanner for logging food; app does not have the same capabilities as the website.

    Since I started wearing, I have become more conscious of my daily activities. I now walk to more places, take the dog on longer walks and have already increased my daily goal. Whenever my friend and fellow fitbit wearer are together and hit our goal we can not help but shout Fitbit!! It seems my world has gotten very busy lately without any time to go to the gym and this shows me that all the little things I am doing are helping.

    Love my fitbit. I wear it always (except in the shower). Just the sight of it on my hand reminds me to keep moving. I'm happy to say that I very rarely miss a 10,000 step day.

    I was given a pedometer at work for a Step Up challenge. I tkept resetting, turning off and didn't count accurately. Tried the one from the previous year with no better success. I read tons of reviews on the Fitbit, and I have been wearing it for the last month and it is amazing. It is accurate, syncs up with other apps I am using and works with anything I am wearing. I would highly recommend it, and I have to several co-workers.

    I used to use the nike fuel band, which I did like, but it broke after a few months. When I heard about the fitbit, I waited until the flex came out and then bought that. Since then I use it all the time. It syncs with my iphone 5 and it's nice to log your food, water, and any activity, including sleep. It's very accurate and the battery life is excellent. It does monitor calorie burning, but I would not say it's as accurate as the Body bug.

    I should have spent the extra money and got the one that has a heart rate monitor and a small display screen. The battery also dies quickly and it's a hassle to have to have all the parts with you to charge it. Overall, I like the way the band fits and that it came with two size bands. I like the app that I have on my iphone where I can check my steps throughout the day and compete with my friends.

    The step-tracking encourages me to move more, and from the sleep tracker I understand more about my sleep patterns...good and bad. It's not easy to slack off when you see the numbers for both steps and calories. I have started losing weight since I vividly see calorie counts attached to my eating habits. Wish I didn't have to remove the tracker while charging 3 hours. I am experimenting with short charges on my laptop while I am reading.
