The longer strap that connects the brushes lasted about a month with just a few uses before completely breaking. The previous (original) lasted for several years and was only partially torn apart. When I removed the replacement strap, it seemed fragile and not the same as it was a month ago. Maybe it was an accident, I ordered another one. Update: This one also took a month. Maybe I misplaced the belt on the center pulley. Center pulley pops out for easier installation. If you don't hear from me within a month, the reorientation has worked.
