I used these outside for regular string Christmas lights and they held up all year until I removed them. I also use them to keep an extension cord tight up to the wall instead of nailing them into the wall. The tape is a little tough to remove and broke on a few occasions, but the clip didn't break. I have also have used them to hang decorations. It holds a bit better than the similarly sized clear hooks, but that may be because they are outdoor use instead of just indoor. Either way, I like using them indoors for decorating if I can.
