Hey all, I hope someone can help me with this. One of my sensors is broke. A quarter got caught in the cluster and jammed into it. IBOT does not repair this on sight. They replace the entire chassis. This is a $3,500.00 repair. Has this happened to anyone else? Does anyone know how I can get one of these sensors? In a few years we may be on our own repairing these chairs so I may open mine up. Any help would be awesome.
