    I bought my fitbit flex 1 month ago and just got an email asking for a review, i usually dont do reviews but i am pretty happy with this product so here is my experience: I wear it every day, even in the shower, It syncs with my galaxy android phone without issues. I love how it monitors my sleep and the website is excellent. i also plug in my food every day. Wearing the fitbit has worked great for me so far. I lost 12 pounds this past month due to the healthier eating and long walks that i am motivated into by the need to meet my fitbit goal. (got to get those 5 led's lit up!) I take it off about every 3 days and charge it for a couple hours in the evening while i am online and sedentary. The website dashboard is full of useful stats, one feature i like is the friends list. I added 5 or 6 friends and have a couple that are about at my exercise level so the friendly competition has been a big motivator on days when i just want to hit the couch and watch tv instead of moving. I can't really think of any negative to say so far, the first time i put it on i had a hard time clipping the clasp of the strap, someone suggested wetting the slotted part and i did that with my finger and it clicked right in, after a few days i leaned how to do it and now i can put it on and take it off as fast as my watch. I do alot of hiking in the woods and haven't managed to break it yet. it comes with a usb sync dongle so you can sync with your computer but i just let it sync with my phone. I read it doesn't work with every phone so make sure it works with yours. It works find on my galaxy S3 android but thats all i've tried.

    Bought for my wife as a Mothers Day and she has been wearing it ever since. She likes the auto sync with her phone and the sleep tracking. Now she wants the next mode up!

    Liked that it can get wet and use while swimming, etc. Only thing is that I was luck having kept my reciept and bought the extended warranty. The 1st time - it stopped charging right before the manufacuers 1 year waranty expired. The 2nd time it was a couple weeks after the manufacturers warranty expired and I had the extended warranty to use due to wireless not syncing anymore. So this is my 3rd one. But I do like it and it has helped me to ensure I do my 10000 steps. :)

    I have had other fitness trackers in the past, but this is the best. The color is great, and I get complements on it all the time. My favorite feature is the vibrate alarm. It lets me wake up without loud alarms that wake up my boyfriend. The iOS app is easy to use and full of useful info, as well as food tracking features that show remaining available calories for the day. This band makes tracking fitness easy!

    Tracks your steps pretty accurately. I bought the watch band to replace what came with the actual product because it didn't seem to sturdy. A few nights it seemed to have come out of sleep mode and didn't track my sleep. Otherwise I love it, makes me aware that i need to move a bit more. I also like that you can add friends and see their steps too for a little friendly competition.

    it is a great product to keep track of step, and sleep, however, it tracks all hand motions even if you are not walking.

    I love my Fitbit Flex! It has motivated me to move and move some more. It is accurate for what it was intended to do. The only thing I wish it did was track things other than walking, like swimming and bicycling. But I intended it for walking and it does that beautifully. It also tracks sleeping which is great too. You are not restricted to just a black wristband. You can get replacement wristbands in a variety of colors.

    I have been wearing my Fitbit Flex Wristband for about 1 month. It is very comfortable, easy to use, and provides accurate information to help me towards reaching my fitness goals. It motivates me and makes the process of getting into shape more fun. The only thing I wish they would add, would be the ability to access more of the information directly on the wristband, instead of having to check on a computer or mobile device.

    Very easy to set-up. Loved the app. Easy to use. Set-up daily goals and found myself pushing to reach them at the end of the day. Battery would stay charged the entire week. Loved the vibrating alarm feature. Looks good. The band was hard to snap in, fell off twice in the first couple of weeks. After that, no problems.

    The product is easy to set up and charge every four days and lasts five days. The product can be worn in the shower and is great to wear. This is the best fitness product out there and tracks sleep. It comes with a two wristbands a small and a large, and a wireless usb port.

    I decided to give the fitbit a try after deciding that I had to start making better choices with my health. I bought this in black and I love it! I wear it even when I go to work! Its tracking has made me want to take long roads back to the train station just so that I can reach my goal for the day. It has encouraged me to walk around the office just to get more steps in. My only wish is that it wasn't so rectangular/boxy, but it doesn't bother me much

    Affordable, basic way to keep track of your steps. I got this for a gift for my teen daughter. This is her first tracker so I wanted something affordable and simple to make sure she would like it, take care of it and actually use it before I spent "Big Money" on a tracker So far so good, she really likes that you can change colors of the band if you purchase others that you want separately. The only time she takes it off is when she showers or to charge it. Time will tell if this keeps up, if it does I plan to get her a top of the line when this one goes out or pass it onto another family member.

    Great device, but band can't be cleaned well

    I purchased this for my wife with the pink band. She absolutely loves it and it synchronizes great with her Windows Phone. There are only two small drawbacks that caused me to drop a star from my review: One: If you use the USB sync dongle in your PC/Mac AND have it synchronizing to your mobile device over bluetooth, the two will compete with each other as the device is synchronizing. It may show, for instance, 1500 steps taken one minute, and then 2300 steps a minute later. We determined it was jumping back-and-forth between PC sync and phone sync and they were getting confused. We disabled PC sync and everything works fine now * Two: the pink band is quickly starting to "dirty" in the rubber material from skin oils and sweat, and we can't find any way to scrub or clean it. She'll be getting a replacement band (3rd party) soon as its really starting to look bad. The cool: She can use her phone to scan UPC symbols on products to add them to her daily diet (provided it has one of course). Its an easy way to have calorie/protein/carb calculations put in automatically
