I wanted to use these foam mounts for a light, hard plastic container which holds a removable light source. After following all of the directions, i.e. cleaning the wall and area on the plastic casing, the whole thing start to come away from the wall then, fell to the ground luckily the light source is also solid plastic and did not break. The wall still has the foam mounting on it because when I started to pull it off it took all the paint with it! this product is confusing because it is the same thing that came with the light holder to begin with, and was much easer to put up and then remove when we moved. There must have been a change in the way they were made.
