But look around online, you never know when you can find a better deal.

love my new fitbit, what a way to track all your daily activities for health

Overall, the FB Flex works as advertised. I workout on a regular basis, so it's very handy for tracking my progress. And, I really like the website and phone ap. 3 things I wish it did, or did better... 1. Does not track heart rate 2. Does not track workouts on stationary bike. Although you can input data manually. 3. Tap functionality is sometimes a bit quirky. I would say if you are an outdoors runner or walker, or just want to track general exercise and movement thru out the day, I rate if very high. If, however, you workout in a gym, as I do, it falls short in many areas. Not sure I'll keep it. I have had it about 2 weeks, and will give another week before I decide.

I like that it tracks my sleep as well as my steps. Also links with My Fitness Pal.

Easy to use, comfortable, and a great motivator to remind me to stay active and healthy

Really nice this Fitbit! Perfect for work-out! I strongly recommend!

Great tracker, it keeps me inline. Had a few week lost 8 lbs.

It is a great product! I would recommend to all. Helps with steps too!

it's awesome....its awesome...makes me to take stairs all the time....

Works great well made amazing device I recommend it for all

When I got the flex I fully charged the battery and begun wearing it. I liked the comfort and watching my steps. However, when I tried to charge it the 2nd time it would not charge or sync to my iphone. I contacted Fitbit customer service via email (apparently the only way you can) and still one week later I have yet to get a reply even after sending the 2nd and 3rd requests for help. I decided to return the flex to Best Buy and exchange it for another, but they were out of them. Best Buy did refund my $ and I just purchased a jawbone up. Hoping for better results. Don't waste your $ with the Flex!!

I love my Fitbit. It keeps me moving and on track!!

The very first review of the Flex on Amazon made that point quite clearly. Second, there is a reason there's no manual: generally, people don't read them. That's why you need to go to the website to initialize your Flex, and, hopefully, read the other instructions.

I loved my Fitbit at first but had problems with charging within the first few months. I did all the troubleshooting but it still wouldn't charge. Fitbit sent me s new one and now less than a year after they replaced it the first time it completely died. Fitbit will not replace it because it's more than a year after my original purchase but will give me a whole 25% discount if I buy another one. The Fitbit I have was I originally over $100 and now it's only $79. I guess they want everyone to buy a new one every year and a day. I'm not happy!

I was really looking forward to getting a Fitbit, but was suprised when I reached my goal, but really did not do much walking. At one point, the app was open on my phone, and at the same time I was petting my dog. I saw the step count go up with every scratch! This darn thing was not tracking steps, but the movement of my arm. Sorry, but I think I'll just go with the S Health that came with my phone. At least that one is quite a bit more accurate.

I am a 160lb healthy woman, I bought the fitbit so I could track my calories and my steps, so on and so fourth. The fitbit automatically counts calories that you've burned while sleeping. (600 a night for me) then while walking from class to class for a day I was on average burning 6000 calories A DAY!!! I didn't run, I didnt excercise, and I just walked to each class (5 minutes apart). I didnt burn 6000 calories sadly. I was really turned off by that feature and I will return it as now it is just a pedometer and I dont want to pay $100 for a pedometer.

After owning the Fitbit Flex for two days, it started logging unlimited steps whether I was even wearing it or now. I tried getting it to stop but it seems like there's nothing I can do. At this point it has 124000 steps by 11:00 am. I can't believe they would sell something that starts acting up after 2 days. This was a real waste of time. I called Fitbit and they said I need the USB charger to reset it, which I only have at home and I don't carry it with me everywhere. It seems like a major inconvenience.

FitBit Flex works well for basic use. Not great if you're trying to track sleep, swimming, etc. Seems to count steps at a faster rate than other pedometers I've used, but as long as it is consistent it will work for me.

Have had FITBIT One for over a year but love the FLEX because it is obvious enough to remind me to keep moving ... yet is not so obvious that people immediate say ... oh you are using the FLEX.

This product is so bad it has caused me to write my first ever BestBuy review. I have had my FitBit for less than a year. It will not charge any longer so it is totally worthless now. I've tried all the tricks I find online (clean the contacts, use tape to hold it in the charger, etc). Nothing works. And it's been intermittent since about 6 months in anyway. I kept thinking maybe, just maybe it would get better, but now it is totally dead and totally will not charge. What a waste of money. Get something else. Oh, and the band around where you put the device in and take it out started splitting within a couple of months.
