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.
