I fell and snapped one side of the plastic arm cuff, that the Velcro retainer goes through. I Krazy glued it and waited 24 hours, half an hour out, snap. Next I repeated the procedure with Permatex Ultra Bond Gel super glue. It lasted for about an hour. Anyone know of a glue that will actually work on this type of plastic? I have the 9x12 coil on now and it is noticeably weightier.
