Both my friends still have the chrome dealer plate holder on the back of their car which looks like crap. Thankfully this comes in a x2 pack for a discount on just purchasing 1.
Super easy install. 2-4 screws depending on how secure you would like to make the plate. Most are held in by 2 screws so i kept it this way. Total install time was about 2 mins. These License Plate Frames are silicone so should be quite strong when dealing with the range of climates in PA. It is a snug fit, not to hard to fit the plate in but it does stretch around it to prevent and shaking or moving when driving. I believe they will not only improve the look of your car but will help dampen noises coming from the rattle of the plastic frames that are usually installed on the cars by dealers.
I only installed the product today so longevity i will have to update the review in about 6 months and see if they are worth the purchase. Considering the cost and it being silicone i easily would purchase them again at this point.
