Buying a chair lift online from these people is dangerous. We ordered one brand and got another. The installer came from far away, left having done an appalling job and these sellers would not send them back to make it right. We did not get the three promised covers, nor warranty materials and an acceptable operating manual. The brand provided has an awful open track that is going to require constant maintenance, no backup battery, and it is bottom-of-the-line. The man who sold it to us was simply in it for "a buck". Watch out for this place. They seem far from honorable.
