    I bought this as a present for my wife. My feedback is from her comments. She likes the small size, but she would like to see how many steps she has taken as opposed to just seeing lights that track her progress. She does like the sleep monitoring aspect. There are no instructions that come with it. We had to search around on the Internet on how to work it. She eventually called a friend who had one and asked her how to work it. The devise works as advertised.

    The Fitbit does a good job of tracking your activity including your sleep time. Easy to use once you figure out all the light sequences on the product.

    It does a great job of keeping me aware of how much I've moved (or not). The battery lasts about a week and a half before I have to recharge it.

    Fitbit is a great tool for motivating you to increase your physical fitness. Keeps track of your daily movements and is easy to see progress on your Ipad.

    I love this product, because I have worked out every day since I got it. I have been able to meet my goals every day and if I can't get out of the house I will walk around the house until I meet my goals. It registers the amount of time you sleep, but once you tell it you are sleeping it is really not accurate when you get up. Once I said I was sleeping at 9, but I couldn't fall asleep so I read for an hour or two, but it was unable to tell. I also don't like the fact that it won't really register swimming movements or aerobic exercise in the pool. I know it works with My Fitness Pal which I use every day to record my food intake and I know it works with its own scale (which I don't have, but it will pick up the weight I enter into my fitness pal app. I am close to 70 now and really don't put too much of a strain on it, but someone who wants more information might need something more geared to their sport. It works really well with the iphone and the ipad. It came with a large and small wristband and the water -- after a shower -- left a big spot in the display window so I cut down the extra large band and that works fine. I miss my watch and there is no actual display but you can use the iphone to see your statistics. It is very hard for me to buckle the wristband by myself and I understand that the extra one supplied with the additional wristbands are made of plastic and break almost immediately.

    Great tracker to keep track of steps throughout the day. Also, it measures sleep which is a bonus. It syncs easily with app. Also the FitBit App also syncs with the MyFitnessPal app so no need to duplicate entries.

    This is an awesome piece for any athlete young or old, professional or amateur. It has a sleep function that tracks your sleep through the night that really gives you a great view of how good your sleep is! Tracks: steps, miles, calories burned, weight goal, sleep, calories eaten, calories left for a goal, and water intake! This thing is awesome sauce! FREE APP! Bluetooth connection to phone/computer!

    My wife uses this to evaluate step activity. She enjoys the ability to accessorize (multi color bands, Tory Burch, etc...) It has helped her realize the lack of activity during busy work days and the need to proactively exercise on those days. The cost is very low relative to the benefit. Well worth it. Grabbed one for my 8 year old too and she's addicted to the numbers

    I wear mine all the time! (I don't get it wet though). However, since I have an older iPhone it doesn't sync but it does come with a wireless USB dongle which I hooked up with my home computer. I can't wait to get home from work and sync to see how many steps I did! I track my food through Myfitnesspal and you can sync them. It tracks your sleep patterns. It's amazing how many times I wake up at night, don't even ask how many times I am "restless"! At $99, it's a great motivator. I highly recommend it.

    I love this fitbit. It is small and concealed for the most part. I wear it everywhere and at all hours of the day. I love the app. I recommend this to anyone who is trying to live a healthier lifestyle!

    I've had this for a couple of weeks, and I'm really enjoying tracking everything. It does seem to accurately track my steps. The band wears quickly, so although I'm glad that they sell other bands, I'm disappointed I'll have to get a new one rather quickly. The sleep tracking is definitely eye-opening, and the tracking is very motivational to keep going. I like it, and I'm glad I bought it.

    My husband and I have been talking about living a more healthy lifestyle, so I got one Fitbit for me, and one for my husband. We both like it, and we have a contest every day to see who has the most steps.

    Great item and great price. Step up the first time and ever since it connects to my phone automatically. I love the silent alarm that wakes you up only.

    The Fitbit Flex was received as a gift. It makes me aware of how much exercise I have or have not done during the day. It is a good motivator.

    Excellent motivator to remind you to walk and move more during the day. This was always difficult for me due to an office desk job. Now I get a message you have been inactive for 2 hours time to take a walk!

    I love this product! An office job makes it harder to move around, this product is definitely a motivating tool. I'm competitive and makes it fun to "outstep" my friends and myself from the previous days.
