Review on Kurgo Car Door Guard for Dogs - Pet Protector for Car Doors, Waterproof & Adjustable - Quick Installation, Storage Pockets - Fits Sedans and SUVs - Black, Grey, Khaki by Beth Brooks

Bought to keep my kids from smashing car doors in the back seat. They do a great job of keeping my kids out of the grip area dirt and greatly reduce scratches and scuffs from kicks or knocks on doors. I did NOT use glue as I don't want them to be permanently attached or ruin the inside of my door (kinda defeats their purpose!). As an aside they don't work with dogs unless glue is used (maybe) as it takes very little to push them out the window and also moving the window up or down seems to move them as well ( the window can't be all the way down without falling out). I love bags and they are great for my purpose.
