If I could give 0 stars, I would. I was so happy to find exactly what I was looking for at Revain when searching the store failed. I opened the package and this time really followed the instructions, cleaned the wall and left it for two days before putting anything in the clips. I used this to hang a bright, painted sheet in my child's playroom. Two days after the return window closed, they all fell in the middle of the night. Scared the hell out of me and my baby. Don't waste money.
