Cheap ones.
I usually buy Anco at WalMart, but I’m going to discontinue the practice. I bought new ones and my driver’s side one had a small tear that left a streak. I got a replacement and that one screeched like a mouse caught in the talons of a hawk. I’m guessing those may have in the back stockroom for awhile.
I bought the “house brand” at an AutoZone and it’s working perfectly.
I’m a stinker for clear windows, so I changge mine 3 or 4 times a year.
