    I like it. I wish it was a heartmrate monitor as well. Not sure it's very accurate re steps. I am concerned about it falling off. Not a very secure closure.

    I love using this but I feel like it may not track as many steps as my boyfriends. You can play around with settings to get it to match your steps and stride length which it neat. Maybe I just don't really walk that much.

    I bought this for my Daughter and it is perfect for what she uses it for at a lower cost. I also liked the fact that it was on sale at a $20.00 discount.

    I love this thing! It shows you exactly how active you REALLY have been all day. Looking at the stats in the early evening motivate me to take the dogs for a walk or something to complete my daily goals. It syncs easily with my other fitness apps so they don't overlap. It's light and comfortable so it doesn't bother me to wear it all day and has great battery life. My only problem was that it didn't sync with my Android but the toggle (which comes with the fitbit) let's it sync perfectly with my computer.

    I ended up going overseas and had to take my fitbit off for a metal detector. I apparently left it behind. I needed a new one fast when I got home. I ended up going to the closest Bestbuy on the way home from the airport. I was able to buy the fitbit immediately and Bestbuy even priced matched for me, no questions asked. Device works perfectly, couldn't be happier with my purchase

    Really good activity tracker. Not sure it is 100% accurate with the number of steps, but when reviewing others, none really are. My wife really likes it.

    The Fitbit flex is a nice fitness tracker. My family has 4 of them currently. This particular one had a major issue but Fitbit replaced it without issue.

    Do not expect a beat all to end all type of product. With a lower price point you get less features but what it does come with is great. It does take some time to set up at first, but it really does seem to help your awareness around eating time. It tracks your sleep time and restlessness. This is a great tool for the newer exerciser. It is a great start to track your progress and meals.

    This tiny bracelet is super helpful keeping me on track of my workout. I have been eating healthier counting the calories and workout much more than I used to. This is a great motivator for a starter in the gym!

    Good Tracker for a Walker/Runner

    The device tracks sleep (which I like) and it tracks steps taken. It also tracks your periods of being "very active" which I don't find to be accurate for someone that does something like Crossfit or weight training. I can have a great workout where I am left out of breath and unable to move and it does not even register. I think this is probably better suited for someone that is a runner.

    Not Worth It

    I purchased the pink one for my mother back in December for Christmas. She only had it for a month or so before it stopped tracking her steps and would not charge. I had a protection plan so I exchanged it for her and got her the black one which lasted a little while longer but not a whole year. After realizing how awful the Flex is I decided to upgrade her to the Charge which is definitely worth the money. The Flex, however, is not.

    I bought this as a gift for my sister, so I haven't actually used it myself. She does tell me on a weekly basis how much she enjoys it though. I have a different device and this one can do much more (track sleep, track meals, etc) than mine can and I paid approximately $40 more for mine. Overall, from what I hear, it's a pretty awesome tracking unit. I'm going to get one for myself when mine dies, which considering I've already had to replace it once within 6 months, I'm gathering won't be in the too distant future.
