    Very difficult to fasten the band. Sometimes won't sync. When it does sync, seems to work well.

    Overall great product. Pushes you to keep up with goals and like the fact it syncs with MyFitnessPal and MapMyRide with added information. I really like the sleep mode to provide data on when I'm moving around/restless to give me an idea on how long I slept and when I'm restless during the night. Very happy with this purchase and highly recommend it.

    This band has an app that can communicate with your smartphone. You can track number of steps, for how long you were most active, calories burned, ect.

    Received mine as a gift and had to get the wife one. Works great and makes you accountable! We have challenges every week. Wish I would have got the one that has more features.

    This is a great fitness tracker if you want to keep track of your basic walking activity. If you do more exercise than walking you would want something different. I work in an office so I love it to keep track of how active I am during the day to then supplement with additional exercise. The dashboard and friend tracking is a nice feature to motivate you.

    I purchased the fitbit flex as a gift to my mom so she can better increase her work out habits with this single bracelet. Functions are great but the bracelet can be difficult to place on your wrist at times. It emails and updates you with your weekly exercise and congratulates us if we hit our daily goal. It can be also worn in the shower but still needs to be cautious to see if its working afterwards. Overall it became a great gift.

    I love my Fitbit. Setting step goals have been a great help for me, someone who is not very active during the summer. I also enjoy the weekly challenges my friends and I participate in. It encourages us, cheers for us, and is fun competition.

    It's just like the Nike fuel-band. I think people like this better because of the link option with the scale. I bought this for my wife. She likes it and I might get one know.

    I like the fitbit - it's way harder to lose than the previous version (I lost two) that just clipped on to your clothes. The battery life could be a little better - you get about three days out of each charge. It ties in well to the other websites - myfitnesspal, etc. It'd be nice if it had a display screen like the other fitbits where you can actually SEE how many steps/miles you've gone instead of having to check the app on your phone.

    She loves it so far. The sleep cycle part is great as it really tells you how much quality sleep you're getting. She needs to charge it every 3 days I think. Only negative so far.

    I am a firm believer in WW but after canceling my membership I was looking for another way to track both my fitness and my caloric intake. FitBit is great with only the one time purchase versus a monthly plan and allows you to add custom foods. Although I rarely use the desktop app, the iPhone app is convenient and helps me stay on track. I particularly like that it changes your caloric intake based on the activity that you have completed for the day.

    I switched from a Nike Fuelband to this. Neither have it quite right - the fuelband gives you data on the device, this does not. This measures more stats and gives more data on the app for the phone - the fuelband does not. This device integrates with calorie counting apps the fuelband does not. The battery life on this device is short - the fuelband has a long battery life. This device does NOT give good documentation on how to read and use it.

    All in all I like the concept. I had a fit, but that did not surrvive my job, so I opted to try the flex. With the exception of the sleep recording it has worked flawlessly untl today. The battery discharged and upon recharging it is no longer tracking. Relative to the fit I think the flex reads a little. high. I attribute this to being based on arm motion versus body motion. I'll give it a day or so then return it on warranty and try again. The software is great, as are the graphics. I do miss the on device read out of the fit.

    I used it to get back to walking/jogging to loose weight. It helped me to track my activity and increase it on some days. It has been a great motivator.
