I like my Fitbit One. I wear it everyday and nights since about 3 weeks. The accuracy is correct - not perfect but I was not having so high expectations for a gadget I keep in my pocket. I like the fact that you can charge it and it's really the one reason why I choose this one instead of any other cheaper pedometer. What's really bugging me is that it's 10 times more expensive than a normal pedometer… The website is nice for keeping track of your activity but *spoiler!* you have to pay even more to access all the features. I feel like a company must give you something that's actually worth your money before asking you for more. They lost me on that one and I won't be buying from them anymore.
