    I LOVE my Fitbit flex! I walk all day at work and i'm not able to carry my phone at work so I had no way of tracking my steps, so I would just guess. Well once I got my FLEX there was no more guessing! I also like that it is able to track my sleep. I have a hard time sleeping sometimes and it tells me how long it took me to fall asleep, how many times I woke up in the middle of the night and also how long I slept. The silent alarm is also an amazing feature. before I tested it out I thought how is a little vibration going to wake me up? WELL IT DOES! and it is SO much nicer to wake up to a vibration rather than WAA WAA WAA WAA WAA from an alarm clock! Go buy this product! what are you waiting for!

    I love my fitbit, but the only problem i have is that my calories burned amount is seriously wrong. Correct me if I'm wrong, but you cant burn 2000 calories while you sleep. The charge lasts a long time, and doesnt take long to charge once it is down. I like that I'm able to add friends and challenge them, it adds motivation to beat my goals.

    Since it is ideal to take 10,000 steps a day I find myself working out a little more just to reach it. It is also great cuz it tracks sleep & how many times u were restless that night since I always feel I did not get enough. Best part is, it doesn't take long to fully charge. And you can channge the look by buying the different colored straps.

    The Fitbit Flex is a good tool for someone who is interested in tracking their daily distance in steps and miles. In addition the silent alarm is easy to use and you can set more than one alarm at a time. This Fitbit is easy to use. You do need the app in order to see your exact data.

    Fun to be able to track my steps, sleep, calories and exercise on my Android phone, my ipad or laptop. I get a weekly report to summarize how I am doing and where I need to work harder. You only have to take it off to charge it and you can wear it in the shower. I am happy that I bought it and would again.

    I love the fitbit because it keeps me honest. I am always checking to see how close I am to my goal and I paired the software to myfittnesspal to keep track of what I eat. I also use it to track my sleep and use the silent alarm. The only thing that is annoying is always having it on. I take it off to shower and wash dishes but that is it.

    I have been using my fitbit for a few months now and have really gotten hooked! I use it for tracking calorie intake, steps, workouts, etc. and it's been really helpful for keeping me on track. Battery life is pretty good so far. I charge it about every 3 or 4 days. Only complaint is that my wife also has one and when we walk together, mine records more steps over the exact same route. Not sure why there would be a difference in the accuracy.

    "Set It And Forget it" - very easy to use and wear

    A great fitness tracker and motivator for those who work traditional office jobs and would like to be more active. Keeps relatively accurate count of steps walked per day, and you can use that # to modify your daily routine to increase your step count. Also tracks sleep, so if you tend to toss and turn a lot, you can see exactly how much/often you do it. Takes a little getting used to when wearing to sleep, but eventually you don't notice it's there.

    It does what it says it does and we are very happy with it. The only reason we chose this one is because most of our friends are on fitbit. I gave them 4 stars because they have great customer service and that means something to me. The reason that i didn't give them 5 stars is the fact that the cost is still a little high in my book.
