My cats had discovered they could open the freezer section of my fridge, usually during the night or while I was at work. I tried tape and Velcro, that either didn't work or made it hard for me to open the freezer. Finally I tried the small Command hooks, one on the body and one on the door, placed sideways facing away from each other. I then used a rubber band stretched across the hooks. They haven't opened the door since. The product is securely attached even with the tension from the rubber band, and I'll be able to remove them without damage to my fridge. Great product.
