I purchased this product about two years ago and frankly had forgot about it until I saw it up for review. It had originally caught my eye as something productive to do while watching a movie and I used it consistantly for about two months. Overall, I can't say I was too impressed with the product. Needless to say, I don't own this product anymore. In my opinion, it doesn't give you a great enough range of motion to really result in a good workout and even after using it for the duration of a movie I was unable to break a sweat. I would probably not recommend this to a friend unless they were the type who just can't stand still and need something to do during a movie or whatnot-not strictly a workout.
