I did, but I would not buy it. It worked great, but once I used it the next day my computer - a Windows 8 crashed into oblivion. I might have just been a rare case, but I really had a problem with using it. I have it and don't use it as I am worried it will 'kill' another computer. Most people don't have this problem. It is motivating, I used it about four days. But I can't afford a new computer every week, no one can. Good luck if you try it.  

A co-worker of mine hasn't been without her Fitbit since Christmas (she got it as a gift). She tracks her stats with her phone and her Kindle, but, she's mentioned that she isn't seeing much progress. 

It is used as an aid, it is not going to take the food away from her.
