    This is the second FitBit I have purchased. The first one finally died after 1.5 years. The product is small enough to not be overwhelming in appearance yet provides a wealth of information when sync'd with your smartphone.

    Purchased for my wife. She loves and uses it daily! She enjoys tracking her activities through out the day both on her FitBit device and an app on her tablet. She is a very busy career woman and mom and she can now measure caloric intake/expenditure, sleep mode, water consumption, and set weight loss goals.

    The product is great if you are good at keeping track of what you eat and remember to tap it each time you go to sleep/wake up. If you want it to do things like keep track of your pulse/heartrate, step up to other models...

    Comfortable and easy to wear. Battery last about 4 days if you are wearing it at all times. I do wish the charging system was different. There is no way to charge it if you loose the charger unless you just buy a new one.

    This is a great basic fit bit but it is worth it to spend the extra 20 or $50 and get the upgraded version that monitors heart rate, and is a little more expensive. This is super basic, super easy, and a little simplistic.

    The perfect gift for my husband on Valentine's day

    My husband is a fanatical hunter so the camo Lifelock phone case and. Belt clip were perfect for him. Especially since it is waterproof, dust proof, and basically indestructible. Since he spends a lot of time in the woods, the camo and black case keeps from attracting any wildlife (or so he tells me)

    This is my first activity tracker and I have to say that it does help motivate me to move. I would buy this product just for the vibrating alarm, it really helps wake me up and that alone is worth every penny of the price.

    I am wild about this FitBit. I purchased the Flex because my main interest was in tabulating my daily footsteps. In addition, it is the thinnest, most "girly" choice of all the wristbands. I have had no issues with its performance, and it does not get in my way when doing almost any type of activity.

    This is a great tracker that is available in the market with features to compete with friends and also an online dashboard that gives me all my data. The app is also pretty easy to use. But I got bored of it real quick.

    I love my fitbit. It allows me to track my sleep habits and steps taken in a day. I always felt like I've walked many miles at the end of a day but with the fitbit I realized it wasn't as many steps as I thought. It motivates me to walk around more and to take stairs. I love that I can set goals for myself and track my food intake. The fact that it connects wirelessly and updays to an app on my phone is a bonus. I have also purchased some accessories and can now color cordinate my armbands. Its easy to use which is a plus as I am not that "techie"

    A more healthier lifestyle

    This was just the motivation I needed to becoming healthier. The option to 'challenge' friends who also have a Fitbit to see who had the most steps walked makes it fun. And the option to be able to look up the calories from the App made it easier to monitor calories in vs. calories burned.

    Great Motivational Tool

    This is a great tool to motivate you to get up and exercise. It links to your iphone and/or computer. Your profile can be linked to other fitness and health apps/ websites. The community is nice as well. You can friend other fitbit users and compare your activity levels as another motivational tool. The only issues I have had with it so far, is with charging. The USB charging dock that comes with it didn't want to charge it, but resetting the charger with a paperclip seems to have fixed the problem. Overall I am happy with the fitbit and have recommended it to friends and family.

    This was a Xmas gift for my husband. I was skeptical about the purchase since he rarely wears jewelry so I didn't know if he'd like the wristband. He loves it, especially being able to track his sleep activity and link to myfitnesspal!

    I thought I moved a lot. Fit Bit showed me I was not moving enough. Now I check it during the day and dance more. The biggest benefit is I have it set to wake me at 5:09 and again at 5:19 Monday through Friday and I have not been late to work since. My weekends and work days are seperate now.

    Basic Fitbit for basic needs

    This is my first Fitbit purchase and I got an awesome deal on it - on clearance plus I had a gift card. :) It doesn't track heart rate (which was almost a dealbreaker) but if you just need something to track steps and calories, this will work for you. It tracks my sleep as well, not sure if it's completely accurate but it's still an interesting feature. I've worn mine almost everyday. I've read some reviews about issues with the strap but I haven't had any issues with mine.

    Whether you're close to your weight loss goal or far from it, the Flex is an excellent device that counts your steps, calculates your burned calories and more. The Flex stands above its competition when it comes to accuracy

    I LOVE my fitbit! This was actually a replacement purchase ( Get the 2 yr BB replacement plan for 14.99 ~ SO worth it) Overall I have had a fitbit since Dec 2013 and I LOVE it. In the first 13 months I lost 45 pounds and being able to track my actual calories burned using my Fitbit was a BIG part of that. You can use the Fitbit app to track your calories too, or you can do like I did and link your Fitbit to another app such as MyFitnessPal. Either way the key to success is the simple math of fewer calories in than out, and this device can help you with that in a big way!!!

    This was for my 10 year old grandson who has started doing kiddie triathlons with his dad this year. He set up the Fitbit by himself on the computer (it was that easy) and created his own account to track his steps and food intake. Pretty simple process and got him more involved in being healthy.

    I really like this activity tracker. The app helps you keep track of calories in and out. I also like the sleep tracker. The one thing I don't like is the band. It is hard to put on so I had to purchase another band.

    Love my fitbit! Easy to use and sync at any time using my phone. The sleep feature is pretty cool too, it tracks how long you slept and how many time you awake or are restless per night. Also love the social feature which allows you to compete and track the progress of your friends who also have fitbits. Only downside is that the fitbit flex does not track flights of stairs climbed like older models. Overall great product!
