    Wish it could be worn around ankle for more accuracy. Sleep function I believe isn't accurate, arm movement equals restless. However, many great features...food tracking; goal setting; does motivate to be more active-you feel the desire to reach your daily goal.

    Easy to use. helps keep track of you caloric, water intake. Also tracks activity, body and sleep. only drawback is I have to use the enclosed bluetooth adaptor on my laptop. Can't use my droid razr or Ipad-2 to upload my fitbit.

    I was really disappointed with the product. I ordered two Fit Bits. The first one I opened for myself and saved the other for my husbands birthday a few weeks later. When I received mine, I set it up and the battery lasted for a week which the instructions predicted only 5 days so I was really excited! Then I plugged it in to recharge it and it would not re-charge. I had really enjoyed using it, so from a usability standpoint it was great. I returned it to Best Buy and couldn't order a new one and they said there weren't even any that they could order on back-order. I then gave my husbands his for his birthday and his is operating fine. The only thing we both would've liked is a heart beat monitor instead of just intensity of a workout. Despite that, I enjoyed the product for the week I had it and my husband is enjoying it as well. I liked that it syncs automatically and that is syncs with Lose It however I never had a chance to do that as we were travelling for the week it was in operation. I also couldn't sync it with my iPhone 4 which was mildly annoying but typical for devices these days. Overall I would say that with glitches like this it would be nice to have enough in production that people could get them replaced. The whole thing was mostly just disappointing and I'm not sure I'll go to the same effort that I did originally to purchase the first two i.e. going to three stores and finally ordering through Best Buy online. I would recommend it with caution.

    This is a great little inexpensive device to track steps, calories, sleep and activity. Works great, however, about every 3 days it has to be charged if you want to keep it fully charged and not run out of battery. However, that is not a big deal and if your charge does get low, you get an email notice, but I never let it get that low.

    At first I was skeptical of how this would work for me counting steps, calories burned, and if I am getting a good night's sleep or not but now a believer and works great hand in hand with My Fitness Pal app

    I like this item. It does a good job for what it does. The Charge has a digital display that includes a watch and shows your exact count of steps/ calories, etc... Charge also has a much better clasp. For an extra $20 the Charge HR has a heart rate monitor
