I buy command hooks every year for my Christmas lights, but this year I am so disappointed. Almost all my lights have fallen off the wall and and when I was applying the strips I had to use a almost all of the extra strips because they weren't sticking enough as soon as I took the cover off. I cleaned my walls to make sure that wasn't it and they still wouldn't stick. I don't know if they changed something this year but I am very disappointed to spend the money on something that won't work.
