    This thing is awesome. It tracks all of my physical activity, and I mean everything I do with it on. Does everything but tell me when my husband wakes me up!

    This is my second Fitbit Flex (I lost my first one). This helps me keep track of how active/or not each day. It is a great motivator. Easy to use and wear.

    I bought this tracker for my wife and after a couple of days I have arrested it. I change a belt and use it by myself. In the past I was using Polar Loop. New one is smaller and giving a chance to keep track of your daily calories income using apps. Minus is weird way and must to put it into sleep mode before sleeping and wake up it too. This is why I score it average

    This device has helped me to walk more often! Everyday I strive to accomplish my 10,000 steps! It also logs your sleep and you can log food, water, and exercise. I find the price to be a little much big I couldn't find anything else on the market!

    The Fitbit is very accurate and the battery is really good. Last about 5 days and only takes about an hour or so to charge. The only thing I don't like about it is it will try to pop off your risk if you bump it up against something or take your jacket off too fast. I wish they made a more secure latch

    Lots of fun and a great motivator to stay in motion. The only issue is that sometimes the battery acts up.

    The Fitbit Flex is a great tool. I have always dreaded walking in the past but now with the Fitbit, I don't want to stop until I see that Smiley face.
