I agree with how useful they are. I have one on a LeSabre and in 30,000 miles it's pretty awful looking.
I used to consider them silly and unnecessary.

I really thought they were more gimmick then useful until I saw mine changed once.
We had Leaves, Dog Hair, and Good Old Dirt CLOGGED in it.
I have ours changed every 30K miles and probably need to do it sooner then that.
