I know two people and one couple that own them.
One man lost 50lbs in six months by doing a routine 5 days a week.
One man used the machine as a sort of rehab for his back and shoulder after a car accident.
The couple - well, the couple have it in their loft. They dust it regularly I guess.
I've tried it - I don't care for it personally. I'm an old-fashioned dumbbell kinda gal.
