This bumper protector covered up the scratches on my bumper, but it is not wide enough to cover the entire bumper from top to bottom. It was only wide enough to cover the top half of my bumper. I had to order a second one so that I can cover the bottom half of my bumper. This is when it becomes expensive because I had to purchase a second one in order to protect the whole bumper. This is why I'm giving this product three stars...the cost is high and it is not wide enough to cover the whole bumper.
