I camp on a Florida beach and attach them (to keep them cooler) to the roof of my van with magnets when camping. I also attached them to the roof of my screen tent. The tape will damage the ends, but they're cheap. It would be cool (sorry) if there was a stronger version with reinforced edge bands or reinforced holes and it was cheap. I've found that they don't store well in their original packaging for long periods of time (in the Florida heat) as the reflective surface sticks to itself.
