    I had been waiting for this product for a long time so i was very excited to finally get it. I was happy that BB had it so I could use my rewards money to get it. ( made the purchase even better). The product is a visable reminder to stay on track so that is great. The manual was non existent so that was bad. Keeps good track of information sometimes it thinks im sleeping when i am not but other than that it is a good product.

    Was a gift for my daughter but she can't use it due to syncing issues with her phone. It will be returned for that reason only.

    The device works very well. It's great to be able to see your progress anytime you want on your phone. I would have given it 5 stars but I'm not a fan of the band. It is extremely clumsy and difficult to close. If they could fix that, it would be perfect. If they do come up with a new design, I hope they make it so that my Fitbit model will still work with it. Other than that, I love it. A great motivator to move.

    I really love this product. However, every now and then things like the vibration from a shopping cart while grocery shopping, or driving, will put it into sleep mode. I thought I've caught it every time, but have not -- which then makes me appear to have been very inactive as steps are not recorded while in sleep mode. Otherwise, love it.

    The fitbit seems to track movement, steps ok. Alarm works good, but the tracking of your sleep cycle has a lot of flaws. The app is garbage, it seems to sync sleep cycle when it wants too, if at all. My primary reason for purchase was just that piece of information (sleep cycle) So keep this design flaw in mind, but I will rate it fairly.

    Absolutely do NOT buy this version of the Fitbit. I purchased this for my wife, as a replacement for one she lost -- the exact same way. The clasp is so poorly designed that the Fitbit can fall off during simple exercise (walking). And unless it hits you on its way to the ground, or you hear it hit the ground, it's gone.

    No, I would not recommend this to a friend
