I installed the brace on my wife's Tikit. It went okay, but I think they should have included a longer bolt for the rear attachment point. Even after discarding the washers, with the brace on, it was a very fine adjustment between having the bolt too tight (rollers don't move). Bolt too loose (nylon in the bolt not in contact with the threads so it would easily come off). Not much room in the middle "bolt just right" (nylon in contact with threads, rollers move) zone.
