    The fitbit is a nice addition to keep track of your steps and sleeping habits. I wish it had a digital watch on it but that options is on the one that they stopped selling. Other than that with the iphone app it works wonderfully.

    This fitbit really improves the activity level for me. For most people working 8 hours a day in front of a computer, it's pretty hard to keep track of how much you exercise each day. Maybe on the weekends you can do something fun but during workdays it's basically minimal exercise unless you go to gym. This fitbit helps you track the steps you take each day and more importantly, the app can calculate the calories in/out so you can keep your body shape (if accurate). The sleep function I have not used much since I do not like having a "watch" on my wrist while sleeping. The only cons that I have is this is not waterproof. So you cannot wear it during shower or swimming. Remember to take it off before getting in heavy contact with water.

    its really comfortable to wear and sometimes I don't even notice i'm wearing it. Battery life is good, i charge it about once a week thought it was cool it sends me an email when my battery is low) I use it to track my activity and sleep patterns and it does exactly that. Im pretty happy with this purchase and price.

    I bought this for my wife a month or so ago, and she uses it every day. She really enjoys the companion app that keeps track of your activity. The one downside to this product: It was a total pain to connect the app to the device. Took multiple tries, and eventually had to delete the app and start over. Once we got it connected, it was great.

    Bought this particular item for my girlfriend as a Christmas gift and she loves it! Bought one for myself also and use it daily. Tracks everything from steps counted to calories burned. The only drawback in my opinion is that the calorie counting feature, which is not the easiest to use. To their credit, Fitbit is working on improving this feature, but it is still not quite there. You can however, link this to other calorie counting apps quite easily.

    This was easy to setup to sync to a laptop and my iPhone. Bought one as a gift for a friend but she is unable to sync it to her smartphone. I Luv the sleep monitoring feature. I also think it is pretty accurate as a pedometer. I also like the way you can set up goals and the app sends emails when you reach it.

    Good tool to track daily activity and give you simple encouragement. Like the "buzz" when I meet my daily goal. For the money it is a good tool, light, simple, works. Interface with Android phone is a bit slow, computer link is much better. Like the ability to track other health metrics such as BP and HR.
