We recently purchased two Rave stair lifts from us medical supplies. The service was great and the agent that assisted us was very professional, kind, and helpful. He did not just sell us our stair lifts and leave us but assisted us in the installation as well. The stair lift are wonderful and serve a great purpose. I would highly recommend the rave stair lift to anyone who is elderly or has a disability in any way. The stair lifts make climbing steps safe and easy. They are great!
