    Not only does the FitBit accurately track the steps you take, but FitBit also has a great website where you can track other activities, and the food you eat, water consumed, and collaborate with friends. It also tracks sleep patterns.

    I have had a fitbit since January and I recently purchased several of these as give aways for a conference that I was attending. This is a great device. I use it to track my steps and activity in kickboxing as well as tracking my water intake.

    I love my fitbit flex..I've worn it everyday since receiving it for a gift. The battery lasts at least 5 days, and it's easy to quickly charge it. The app works great and this product is a fun way to help you stay motivated and active.

    I have used other trackers and this is by far the easiest, most comfortable, and user friendly. I can track on my iphone as well as my computer. It even wakes me in the morning after tracking my sleep. No more need for an alarm clock that wakes everyone else up. I bought the annual subscription which is not necessary, but gives me detailed reports on everything from sleep to activities to nutrition information. The Fitbit Flex also syncs with MyFitnesspal which is helpful. I was lucky enough to buy the very first unit in Hawaii and have been very happy with it.

    Love the Fitbit Flex! Purchased it in December 2014. Also purchased the extra bracelets. Easy to use, comfortable, and is accurate in collecting and storing information. Sales rep at Best Buy was helpful with his input and suggestions.

    I love my Flex. I tap it, & I know instantly if I'm 20, 40, 60, or 80% to my goal of 10,000 steps per day. It's comfortable, easy to charge, and it's practically water-proof.

    I was unsure which device I wanted, but decided on the Fitbit Flex and am glad I did. I love that I can customize weight management and track my calories, along with my steps per day!

    Loving my new Fitbit Flex! Bought it at Christmas time to participate in walking program at work in the New Year. Holds a charge about 4 days so needs charging mid-week. Very light weight, barely notice I'm wearing it. Surprised at how accurate the tracking is and the data about sleep cycle. Had no idea how much active/awake time during night. Wear it almost 24/7 and plan to continue.

    I love my fitbit! It makes me aware and accountable. It encourags me to walk more especially when I'm nearing 10,000 steps. My fitbit also makes me more competitive with my friends who have them too. Easy to set up, charge and use.

    Love the FitBit Flex. Conveniently tracks steps, calories burned and food intake (via phone/pc). The only thing this is missing is tracking flights of stairs climbed.

    It is worth the money. It does everything what it says in commercials and also on the Internet. It's keeps tracks of how many steps I take in a day and also how many calories I burned as well and also keep track of my sleep as well.

    Love this fitbit, find it very motivating and encouraging! Easy to operate, and set up. Put it on first thing in the morning, and then forget about it, always check to make sure I have met the 10,000 steps but most days exceed that.

    I was given a Fitbit as a gift from my son last Christmas. This Christmas I got one for my son and he is using it everyday. It tracks every step you take each day and also how much sleep you get each night.. It is a great product.

    I had a FitBit One prior to this so I will also do a sort of comparison while saying the main features. It integrates nice with IOS or Android devices giving you real-time data at anytime. Downside is that you need to keep bluetooth on so decreases batt life of your phone/tablet. Another nice feature is that once sync'ed with 1 device (say your iphone), statistics are available online and in another devices (i.e. ipad). The sleep pattern is great to understand how much and how well you sleep. It has great a HUGE difference in my behavior and helped me understand why I feel tired sometimes. The Fitbit One has a tracker of stairs where the Flex doesn't but not a major deal to me. The biggest downside is that the battery in the Flex lasts for about 1 week where the One I could go 2 weeks or even more. IT wears nice and very comfortably in the wrist and water proof (I Bath with it sometimes and its still alive!) 4 Stars in accuracy is merely because I have not measured that. It sounds s bit high (especially on calorie measuring) but I can't say whether it's right or wrong. The "screen" does not show any text, only small dots with your progress in 20% ranges

    The tracker itself is great, with the great options of tracking sleep and silent alarm, it almost makes it a complete tool for beginners. I was impressed with the silent alarm feature. The step tracking feature might not be the most accurate as it is based on body movement, but the idea is to make you active, so if you move, it doesn't matter if you are counting steps or not, the most important is to stay active. The band could be a "watch" type of band instead of the clasp they include, but you can always get more, or different bands online. In general I am very impressed this the Fitbit Flex.

    The fitbit really keeps me motivated to keep moving. Love to keep track of my steps, food eaten, water intake, and sleep. And since my friends bought one two it's extra rewarding to get the most steps of our group every week.

    Excellent product and yet so simple to use. Just charge the module, install into the bracelet and wear it all the time. iPhone setup is as simple as the module is to wear.
