I was looking for a cleaner with which I not again smear me the display, so I searched and found the cleaner of rye, therefore ordered here and fix as usual Amazon. The cleaner is really very good and I believe not in vain promoted from reputable manufacturers, my laptop and see Tv in any case like the first day, very good cleaning effect and no streaks. I give it 5 stars, who looks Durchblick, buy!
