I own it, I bought if off ebay, lot cheaper! I love it, I get bored easily, so I switch that up with a lot of other stuff too. I have a lot of Tony Horton videos though. THey are all very good. Results will vary, they also give you a diet plan to follow to lose the most weight. I only need to lose like 5 pounds, so it will be harder for me, if someone needed to lose a larger amount of weight, you would see results. I do at least 30 minutes of workout though, dont just do one, it tells you which videos to do together to get the best results!
