My mother is wheelchair bound. When there is a problem with her chair, it is a major problem. She can't get around. She is on Medicare, which we were told by other companies would not cover problems with her chair. We've dealt with different companies and not been satisfied, but Advacare has helped me out more than once. My mothers wheel came off and the nut was lost. It is not just any nut. Advacare gave me 3 different ones and told me one should work. It did and they did not even charge me. Recently the button on the control arm started to go out. They are very expensive. Advacare went out and assessed the chair and within a short period of time (considering the hoops that have to be jumped through), had my mom up and running, or at least her chair. I would recommend this company to anyone. If you've had to wait for people from Kansas City or Olathe and then be disappointed, call these people. They really do care.
