Pack-20 Car Door Shock Absorber, Thickened Silicone Sound Insulation Buffer Protection Device, Rearview Mirror Bumper Multi-Functional Anti-Collision Sticker, Universal for Car (Black)

Work great for areas that might have metal to metal contact. It didn’t work on all of my vehicles, but I assumed that is because of their design. It seemed to work best on a door jam that has a nice clean flat surface in an area of tight tolerance in my testing. It wasn’t crazy different afterwards but it might depend on your application.

I put these on 2 different cars and I couldn’t tell a difference on either one of them. The doors seems to close just as hard as before I put them on. I was very disappointed, I really hoped they would work.

These do a really nice job if you have spots on your car that could rub together. Just place these where you need them and they give you just enough space to provide a cushion, but doesn't impede any latching mechanism.Adhesion is good. Material is soft and squishy and will bend to take on a curve if you need it to.
