We used some in my daughter's room to hang a pocket thing for her doll stuff. It didn't hold though (too much doll stuff) and when I took the adhesive off, it took the paint right off to the drywall. And it was only on her wall for about 2 days max.
I ended up using a nail on one side (where there was a stud) and a monkey hook on the other. So far, so good.
