I used the medium command hooks in the kitchen to hold my pot holders while living in an apartment and when I went to move I took them down and they took the drywall down with them. They left a hole in the wall the size of a quarter. I was very disappointed. I thought they were supposed to come down clean and not take the wall with them. I have used all kinds of command products for many years and have never had this problem before. I am not sure why it happened this time but, I hope it never happens again because I love command products. [This review was collected as part of a promotion.]
