I used the 3 lb hook to hang my Christmas wreath this year. I wanted to use these because they were advertised as strong and would not harm the surface. After about a week, my 2 lb wreath was lying on the porch was some of the branches pulled out. The hook had come loose, leaving only the adhesive strip on the door. In trying to remove the adhesive strip, all the paint came off underneath. Very disappointed in the product!
