Whenever my car gets hot and I leave the sunshade in place with the visor down, the mirror falls out. I’ve tried several types of double-sided tape, fabric, clear, and 3M, but none lasted more than a couple of weeks. I’m considering a stronger magnet, but since there’s a PC board in the visor, I don’t want to risk using super glue. Has anyone else had this issue and found a long term fix?
