Hav found chair to be fairly dependable. Batteries last about a year. Go to battery store and get Delco or similar. They will warranty for at least a year. There is really not much to these chairs. 2 batteries, 2 drive motors, controller and frame/seat. Have had some luck sourcing parts on Craigslist or eBay. Lot less expensive than list. Like any vehicle they need maintenance and cleaning. Latest issue is flashing controller lights indicating limit switch on drive motor not making when in drive position. Wiring diagrams are nonexistent but will figure out which wires go to limit switch in motor and probably jumper out. Overall have been satisfied with product but company sounds more like a Medicare scam.
