This is the second time I have tried this product. I really wanted it to work so I could decorate my new home without making holes all over my walls. I followed the directions step by step, but the product refused to stay on the wall, even if I didn't hang anything on the hook. I would stay maybe ten minutes and then fall to the floor. I tried a few different times using a new strip each time. I did not use on wall paper, the surface is not vinyl, walls were not wet/humid and the temp. in my home is about 65 degrees F. Very disappointed.
