I bought these hooks because I was thrilled with the fact that they are clear. Being a college student, I am all too familiar with using command hooks to hang up things in my dorm room (we are not allowed to put holes in the walls), but these fell short... literally. They never stayed up for more than a couple days. I even tried letting the hooks stay up for 48 hours before putting anything on them, but they still fell. I've used almost every adhesive sheet in the pack, but only one of my hooks is still sticking to the wall :(. My white hooks, however, are still going strong after a month.
