    I am a active person, enjoy swimming, cycling, walking, hiking, weight training, and qigong. I bought a fitbit for my husband to encourage him to walk more during the day and he loved it and although I was skeptical about the utility, I finally bought one for myself and have been hooked every since. I am less interested in steps or distance walked and more interested in tracking calories burned and monitoring weight , hydration, hours slept, and caloric intake. Fitbit has served me well. You can easily enter in activities to add calories burned and can easily add in your foods consumed. And it helps you be aware of what you are doing and what you are eating and strive for a healthy balance. It sends you congratulatory messages and the app for the smartphone is great. We also bought the Aria Wi-Fi Smart Scale which works great and provides not just weight but BMI calculations.

    I have fitbit one and I was super excited when the fitbit flex came out because I was always worried about losing or washing my fitbit one. I've been wearing them both to compare and contrast. I like the fact that I don't ever have to take the flex off. However, I am concerned about moisture staying in the area where the dongle is so I wipe it out after every work out and don't even attempt to wear the flex in the shower. I wish the flex has a display like the one but the app is great with showing data. I can't quite figure it out but the flex and the one must have different algorithms because they never report the same steps. The flex doesn't track flights of stairs at all. Over all I think it's a decent product but I was VERY disappointed that the wrist band broke within the first 30 days. I'm planning on taking it back to Best Buy. Since the fitbit one is still a great tracker I'm considering exchange the flex for something other than another flex.

    This is so awesome to track your daily activity and encourage you to get the fitbit to vibrate after you achieve your goal. Plus it records your sleep which was extremely enlightening.

    I've been using the Flex for about a month now and it has opened my eyes to my personal habits and their impact on my fitness goals. Over time patterns start to emerge (e.g. historically sedentary days, high calorie situations, times of less productive sleep) that can really illuminate areas for improvement. I really appreciate the up-to-the-minute tracking of calorie intake against goals. It even tells you to get moving again if you exceed your daily calorie goals. My only complaint is that you still need to manually enter most foods and as far as I can tell the mobile app has limited functionality. The database has many foods but I find myself having to spend time calculating nutritional content particularly for homemade foods that contain multiple ingredients.

    It's a step up from the Zip that I owned for a year because this will track your sleep. But I was disappointed to find out that it didn't track stairs. I would 've considered the Fitbit One instead. It's nice to wear around your wrist so it doesn't get lost but I feel like I have to wear it in my pocket when I'm on the elliptical. I have a hard time to get active minutes to register. Pretty expensive pedometer.
