    Very easy to use, since the last update it now records exercises. I no longer use the map my walk program. The sleep mode would have to be my favorite. Now I know its not just me, for the mornings I wake up sluggish.

    I did a lot of research before choosing a fitness tracker. This one had everything I wanted at a good price. It is easy to use with my phone. I like that I can share my fitness progress with other fit bit users for some friendly competition. The sleep tracker seems accurate and is useful.

    The Fitbit Flex is a great little fitness tracker. I could hardly tell I was wearing it, it is light and fits well. It tracked my activities better that I expected. If you can afford the $100 price, I would recommend it.

    This is a greater fitness tracker. My company is pushing a wellness program in conjunction with our health insurance. Initially I purchased it for use with that but after I got it, it became slightly additive. Can I make my step target, can I make my workout target, etc. It helped give some extra drive to do more. It easily tracks step, distance and number of above average movement minutes. It also calculates calories burned through out the day. It allows you to track your calorie intake, you provide the number of calories, your calorie "budget" intake minus burnt, and your water intake. You can sync up with either your computer through the included dongle or through blue tooth with your smart phone. I've used both and either works well. I use my phone the majority of the time. Sometime though it takes a bit for the phone to sync and at times blue tooth has to restart to pickup the tracker. But overall I really like the product and I recommend it to anyone looking for a fitness tracker.

    The Fitbit was motivational at first but it's too hard to enter all the calorie information if you really want to track your calories in and out. I also think the model with the clock would be more useful, as I'm always looking down at my wrist to see what time it is.

    At one point, it wouldn't turn on after I recharged it but customer service helped me reset the device and it was as good as new. Also the band broke off after less than a year. Those were my only problems.

    I primarily bought this for my boyfriend . He started to be health cautious and wanted to keep track of his steps and calories. It's great! You just leave it on and it does all the work for you. It's water and sweat proof. I even got the extend warranty for a great price! This is a must have!
