I had these recommended by two friends who had seen the advertising but not used them. I went to my local hardware store looking for a damage free way to hang greenery over my new front door. It was 65 degrees when I applied them per the directions. After waiting more than the recommended hour I hung the decorations over the door and went to bed. This morning of the 6 had fallen and tonight 3 others had fallen. Seems like a great idea, but it did not work for me. Now I have to start over and replace broken ornaments to boot.
