For the cost I cant find a better mf then the costco ones. They are cheap enough to only use each towel one time and throw it away. Im not comfortable washing any towel and reusing it multiple times so these work out perfect for me. I just went and restocked and the mfs have been changed to much softer and thicker mfs that i really like. If you dont want to use them then dont use them. I own two black cars and they have not scratched them, even when forcing lsp off. If you havent tried them go for it, dont listen to the few people who just dont like them because they are cheap.
