PowerLegs review: Exercise for legs and feet

I bought the powerlegs in may. A couple weeks ago the massager started getting loud and rough. Don't know what to do about it but it should have lasted more than a few months. Would like to get it fixed without spending a fortune. I paid a lot of money believing it would help my feet and legs but it sounds like it could quit at any time. I would appreciate some help from tristar as soon as possible. Please get back with me soon. I am retired and can't afford to buy another one. Thank you
