    I bought this for my wife and she wears it 24/7 except when charging it. It provides constant encouragement to make healthier choices and rewards those choices at the end of the day when totals are tallied.

    I love my Fitbit. It is small and it is smaller than wearing a watch. it is light weight and most of the time you do not even know that you are wearing it. Great way to track your daily life and goals.

    Got as a gift for wife and she loves it. Easy to set-up and use. Easily links with phone or tablet. Full charge lasts 4-5 days. Gives her a pleasant surprise when she walks more than she thought.

    Great Activity Tracker

    I love the FitBit activity tracker. It counts your step activity each day and syncs wirelessly back to most smartphones or tablets. You can also use the included wireless USB receiver on your laptop or computer but I find Bluetooth syncing to a tablet or phone so much easier. The software for tracking is great and includes the ability to track calories in/out, sleep quality, water consumption, etc. And the fact that it's always on your wrist is a constant reminder to get out and move to keep yourself fit. It's not perfect but I find that I exercise more now that I have it.

    I was not sure that I would use this very much so I purchased the lower priced model of all the Fit Bits. It turns out just having this on my wrist reminds me to take extra breaks during the day to get up and walk and encourages a friendly competition between the girlfriend and me. The device itself is great, no issues at all. Battery life is good for about a week between charges. It comes with 2 size bands that have a nice secure clasping feature on them that uses a metal insert not just 100% rubber. I was initially afraid that the rubber would pull on my skin or hair on my wrist but it does not and is very flexible. I would definitely buy this Fit Bit again if I had the chance to do it over.

    I bought the flex wanting something to track calorie intake and burn. It's pretty sensation even on the dominant arm setting. My lawn mower puts it in sleep mode. I wish it would detect sleep instead of having to manually do it. I often forget. Good battery lofe, charge about once a week. Has trouble connecting sometimes, have to restart Bluetooth a couple times. All in all a good product. Next one I get would be the charge HR.

    Good entry level fitness tracker. It has decent battery life but don't go on a trip and forget the charger. You are limited to the USB dock once its dead, unless you travel with your laptop. Good luck finding another charger. I found you can get three almost four days out if one charge if you decide to leave it on. You cannot swim with it on so if you want something that captures all your exercises this one may not be for you.

    I use it mainly for monitoring my steps. I have used for sleep, but I could not get use to the band on my wrist. The sleep monitoring was useful and evidenced what I knew that I was a restless sleeper. It has made me more aware of my lack of movement and motivates me to achieve the step goals I have set. The app also has items you can edit/track, that do not sync, to complete your exercise program. The battery life is good; wish it was longer. When the battery is low it takes a long time to sync or does not sync at all. So, stay charged.

    Great value. Truly counts your steps I tested it. Not sure about the calorie burning but that's ok. It also shows you how long you sleep and how well you sleep. Great motivator to keep moving all day!

    Love the sleep tracking and the instant gratification buzzing at 10,000 steps! Takes awhile to get used to having it on your wrist but then you forget it's there. Excellent tool to keep you motivated.

    Have yet to have issues with the Flex. Make sure you measure your stride and change it in the settings to get a more accurate reading.

    Overall this is a great tool to keep up with your steps. Although sometimes I think it's not completely accurate. It's also interesting how it measures your sleeping patterns, that seemed to be pretty accurate. If you really want to be dedicated to health and fitness, its great because you can log your exercise, water intake, food intake all in the same app. There is no need for a separate app to log your calories!
