Great product/bad application [SEP] I debated on 3 or 4 stars. But because I have to fork out money to make this work it gets 3. I for the life of me can't figure out why they don't provide a strong sticky strip. I have attached to my wall corners and it come off the wall. It not only doesn't stick well to the wall it doesn't stick that great to the plastic. My cats do love these and I will have to fork out money now for secure sticky strips.
