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 Tammy Jackson

They seem to work pretty well. My dogs haven't pulled them from the window yet. The real test will be the journey ahead. As the description says, you might not want to use them if you have tinted windows as the plastic tabs can scratch them. I haven't had any problems with that. Don't expect to be able to raise or lower the window after installation. You will most likely scratch the tint and the plastic tabs that hold them in place, nor are they long or thick enough to stay in place when the window moves. They fit well from side to side but are quite short top to bottom. For the record, I put them in the back doors of a 21'21 Sierra 2500HD and they barely fell halfway through. Also, I haven't used/haven't used/probably won't use the included double-sided velcro.
