    I would buy it again. Maybe the clip on version if you don't want anyone to know you are wearing one.

    Love the feedback that this device gives. Had to go to the FitBit website on my iPad in order to download the app because it wasn't in the App Store

    Does everything I expected, except I don't get any thing about sleep. I upgraded from a lower device and maybe the software didn't load properly.

    Great fitness trainer for the money. I wish the battery would stay charged longer than a few days, but, other than that, it's awesome.

    Accuracy, Battery life, Ease of use

    Rated 5 out of 5 stars

    The most accurate of them all thus far!!

    I've had/tried almost all of the trackers on the market (Jawbone Up, Withings Pulse O2, Old Fitbit, and Body Media) The one is THE absolute best so far. Note all comparisons were done while wearing both items on the same arm at the same time. As it compares to all the above listed this one has been the most accurate and easy to use. This one is truly waterproof as it is advertised, the Jawbone UP when it gets wet has a tendency to stop working or need to be charged more often, the Withings Pulse O2 is advertised as waterproof but the packaging says not recommended to wear in the shower, the old Fitbit One was not waterproof at all and I don't remember what the recommendation for the Body Media was. Any of the Fitbit products syncs with MyFitnessPal, Digifit, and The Withings Scale so I only have to do data entry into one program. I LOVE that I can track all my activity and food in one place its a snap to stay on track. The battery life is WONDERFUL as it compares to the others. I wear my Flex 24/7, I use it to track my sleep and the battery will last at a minimum 7-8 days without charging. My only wish is that it would buzz, vibrate, or alert some way that the battery is getting low. That's not a deal breaker because I have the app that syncs on my iPhone and it shows battery level just fine. As far as ease of use it couldn't be easier, sync the Flex with the computer, follow the directions, put it on start tracking. It is recommended that you measure your stride... The app that comes with Fitbit is great it shows everything and sends little notes of encouragement, and emails letting you know how well you've done. Try it!! You won't be disappointed.

    I emailed fitbit asking about a possible larger wristband, and although were not yet selling them, they were very responsive and sent me one to use!

    Keeps track of everything. I use it all the time. Good counter works the best. Sleep tracker is ok. Not sure how or when it's on to go to sleep.
