    I received this as a gift, I wasn't sure if I needed or even wanted such a device. Now I find myself constantly checking my activity status and pushing myself to my goal. I would suggest anyone to get this device.

    Great band. Makes you strive to get to 10,000 Steps. App is easy to follow. I like tracking my sleep pattern. Tracking your food is also easy to input and tracking calories intake verses calories burned. I did purchase a buckle type band that I like better than the original.

    I have had this product for over a month, and so far I have no complaints. It has encouraged me to eat better! I know it isn't much but I have lost almost 4 lbs since I have had it. I have been a little more active too but that's mostly because the weather is getting warmer, so I'm doing more outside. The only down fall is that the step counter isn't always accurate, but the distance you walk is. Also you have to remember to plug it into the computer/laptop to charge it once a week or so. Other than that, I would say it's a great product!

    This was a gift for my wife. She can't be more happy with this device. It allows her to maximize her non-workout time into productive and a structured workout "filler" so to speak. Combined data paints a great picture for her to use in tailoring her workouts maximizing efficiency.

    If you really want to know how much you're keeping in motion each day & the quality of sleep you're getting...this is a "must" for you. I'm not a fan of wearing things on my wrist, but it is so lightweight it's not bothersome. The only time I take it off is to charge it. Love it!

    I bought this for my mother because I had heard so many accounts from people I know of how much they love the FitBit. My mother fell right in line with everybody else. It's a great product that motivates you to be healthier, exercise more and sleep better. This will improve your life.

    been using it for about a month, once you calibrate your steps it is very accurate (calories burned were very similar to what my heart rate monitor recorded). very cool to see how you sleep, that's not as accurate, but pretty good, said i was restless when i was actually awake a few times, but pretty good. the food tracking is not very good, but I just linked it to myfitnesspal and theirs sync's over. along with any heartrate excersise i customer service is awesome. I lost my charger cable and was trying to locate a replacement, fitbit offered to replace it for free, very nice, just waiting on that now. all in all for a 100 bucks, great investment.

    This has got to be simply one of the best purchases I've made in the lady few years. From the easy setup to daily use this is a no-brainer for anyone who's on the fence about this purchase. It syncs perfectly with my LoseIt App and really makes it enjoyable to own and use. I love the alarm function because I wake up at 4:30 every morning and the vibration alarm doesn't wake my Wife up when I have to get up. Although it is a little creepy, if it doesn't sense you moving it will go off again like some sort of "big brother" alarm telling the citizen to go be productive. If you're considering this even a little, I say go for it you will love it.

    This was for my wife, and she loved it! I watched her use it for a few days with the Android app and loved it so much that I went and bought the Fitbit Surge. It has really motivated me to work out and watch my diet.

    The fitbit is hard to get on. It takes some effort to secure the wrist band. Once on, it stays on very well. I like the way it keeps track of your progress, it is a great motivator. It seems very accurate in keeping track of your activity. There is somewhat of a learning curve. It took me some time to figure out how to use the sleep monitor. I question how accurate the intense exercise record is. It seems that when I have been active enough to get my heart rate up it doesn't record all of it.

    Overall this does exactly what it's supposed to do. Count steps. If you want a more true tracker of activity and exercise a heart rate monitor might be a better route. I do like that I can connect this with MyFitness Pal for calories since I was already using that tool. It records very active minutes, but I get those minutes just walking my dogs and I don't know that I'd call that "very active"...continuous activity, yes. Unfortunately I have days where i don't do much, and this confirms that and inspires me to get going! Sometimes just seeing only 3 lights illuminated (out of 5) gets me off of my butt! A friend has the green band and the ends have gotten dirty and we've not figured out how to clean it up. I have the slate color and it looks pretty good still.

    Great fit tracker for the "common" person

    When I say "common" I mean someone, like me, that is not a gym rat: I needed to be more active in order to lower my blood pressure, so I got this tracker after reading many reviews to help me record my progress. It does the job superbly: you can track your steps, your weight (manually), your exercise (manually, too, but if you run outside it is a similar program that Runtastic), your water intake, and your sleep. The wristband is nice: not too bit, so it doesn't say "hey! look at my fitbit!!!! come and be annoying or steal it!" I bit of a warning: try to get it wet the least possible amount. It gets a bit weird after a shower.

    I bought this because of all the rave reviews I read and got from a co-worker who uses this same device. It is very user friendly. You do however need a computer and wifi access to set it up initially, but, after that it's not a problem. I love that you can sync it with your mobile phone whenever you want an update on your progress. I only have to charge it once a week for a few hours then i'm good to go. I love the sleep tracking capability. I never knew how much I woke up or was restless until I got this tracker. It even tells me how long it took for me to fall asleep. Adding your daily meals is very easy although the selections are slim.

    Great product that helps you as you begin to lose weight since it helps you keep track of your activity and food intake. When used correctly, you have a mini journal of your day's intake and expenditure and lets you know how to move forward. I recommend it to all my friends.

    I've been wearing my Flex for a couple weeks now and I like it. It's good to keep track of steps and know when to make the extra effort to hit a goal. Battery life has been good, easy to set up. Sleep mode is not as good as I hoped, but I'm still learning about it. It's a little tricky to enter and exit the mode and then once you have results, you have to interpret them. What do I do with the information that I was restless 6 times for a minute each? Plus it's hard to see exactly what time.

    It's a good piece. It was a gift for a friend who wanted to watch their activity. Keeps track of simple activities but can be cumbersome when switching from treadmill running to outdoor running and biking.

    It has everything I want. The bracelet is simple and has a solid color, making it easy to pair with clothes. It senses sleep, and monitors sleep pattern, not just the hours of sleep you had. You can also enter your food and water intake and customize how many calories and how much water you need in a day. I haven't tried logging my exercises but I can still track my steps anyway. You can also sync this with other apps and join goal-oriented programs for redeemable points.

    Really enjoy my Fitbit Flex. Makes me think more about keeping active - taking stairs instead of elevator, etc. Wish it came with more instruction. I feel I have a lot more to learn about how to use it.
