Query: THIS SUCKS!

Bought this product and it didn't stick at all except to one wall in my son's room. Bought some more thinking that maybe the wall wasn't completely dry. Waited a week and tried it again, same result. Called Blue Mountain (the company that makes it) and was told there was nothing they could do and to call Amazon! I'm like, "It's your product?!!" DO NOT BUY THIS PRODUCT!!!!
