I was full of anticipation for the small lens cloth, because we for years using a ALCLEAR cloth that window wipes perfectly clear. But the lens cloth has both been chasing us a fright: any cleaning with the cloth causes smallest fibers remain on the lens back: At first we thought our glasses had scratches, but fortunately there are "only" small, but very stubborn adhering fusselchen. Even after repeated washing occurs there is no improvement.
Too bad! But the cloth, I can not recommend unfortunately :-(
