    Personally, I love the sleep tracker. Got to me rethink my sleep schedule which has helped me be more awake throughout my day. I haven't quite figured out the activity tracker but the step tracker is great. i find msyelf getting up from my desk to walk around, more than I ever did before.

    The band is not so easy to put on with one hand. Step counter to far down on the menu Fitbit phone app. menu, should be right under calories burned not way down under water intake. UP 2 had it like in first place so you could see your progrees without having to scroll down.

    Bought this a couple years ago for weight loss/health, and am still using it, although I've had to replace the rubber bands a couple of times, since they crack a bit too easily. But overall, still loving it! Keeps track of steps and sleep cycles. Basic but good.

    The good news if you enjoy monitoring metrics and are disciplined in maintaining them it measures steps taken, distance walked, andtime sleeping. You also have the option of manually monitoring caloric intake. The bad news the calories burned are totally inaccurate. I was away from my computer and the Bluetooth connection for several days so that the information on the dashboard could not be updated; however there were calories burned monitor during this time frame. I must say bit disappointing. It would be expected that the calories would be a calculation based upon steps taken, weight, and intensity. This was obviously not the case. I said below that I would not recommend this to a friend this is debatable if you understood what you are investing in. There may be better products on the market.

    The Fit Bit Flex

    This is a cool item and I like a lot of what it can do however this fitbit has a lot of issues with syncing and updating. It also doesn't keep track of your heart beat and accurately track your calories unless you're running. Body building doesn't register. However the sleep tracking is very nice, I didn't realize how little I actually sleep.
