Just curious, what style of tire and on what kind of roads are you driving. I have the Mopar flaps with about 11000 miles on them. I have checked them a few times to see if they are collecting stuff as others have noted. So far, nothing. However, I have the OEM Goodyear, non-aggressive tread tires and have not driven on any dirt or gravel roads. For my purposes, they are acceptable. The slots in the bottom are plenty large to allow hosing out. I agree with others, in that for me, I like the appearance better than the Weathertech or other brands, but I also agree that they are not for everyone. I am surprised that you are so angry about the ones you have, since they were probably an aftermarket purchase. Weren't you aware of the limitations when you bought them?
