We had professional family pictures done, and the frames they gave them to us in are not able to be put up with nails or standard hanging hooks. I then remembered the commercial I saw about picture hangers and immediately went out and bought some. The hanging strips were extremely easy to "install". My pictures do not swing sideways on a nail, so they are always straight. Nor have they fallen off the wall even with two rowdy kids. Now my pictures are hanging in our living room with no damage to the walls or the pictures. I am excited for using the other command products I have purchased.
