    My son who was turning 12, and is really fit, but wanted this. Honestly I didn't think he needed it, but if he is that interested in fitness, why should I judge? He has thoroughly enjoyed it, and is always trying to get his steps in. Also loves to track his sleep.

    I really like this, helps me keep track of how active I am during the day, and how well I sleep at night. The only downside is that any activities that don't have arm movements or ones in the pool have to be manually entered.

    When I first decided to buy something to track my sleep patterns as well as my steps I did my research. The best thing is that I can use My Fitness Pal with this device. I have severe sleep APNEA and I can track how well my mask is working with the information collected by the FitBit.

    I'm not a health crazed person. But my Fitbit helps me to push myself a little each day. Having sleep apnea, the sleep tracker helps me to see when I have difficulty sleeping and can look for solutions. It has also helped to control my eating habits. Love my Fitbit!

    I purchased the fit bit pedometer first, then was intrigued by the ability to monitor your sleep with the flex. I love being able to wear the flex like a bracelet and not have to worry about forgetting to clip it somewhere. I also love that it is water proof so I can wear it swimming!! :)

    If you decided to jump into the wearable tracker arena, you'll no doubt come across Fitbit. They are the 800 pound gorilla in this space - and it's not by mistake. This unit works flawlessly, it doesn't get in the way, has great battery life and flat out works.

    I was debating between the Force and the Flex, but after a lot of research, decided to get the Flex. I couldn't be happier. It helps keeps the motivation up. Also love the fact that they have a great iPhone app to track progress. I wish they come up with an official windows phone app
