The product description speaks of a "moiré effect" and that the "display representation ... only slightly altered" is. That's quite a trivialization, also writings are blurred and some menus as with metallic colors painted car. After less than one day I lost and discarded the sheet again, not my thing.
For the provider "HandyNow" I have here simply times cudgels. After this negative assessment product for which the dealer was nothing, he enlisted voluntarily by mail, prompting a free replacement a "Crystal Clear"! And that at a price of 2.05 items (which he also refunded) inc. Despatch! Whoever strives for customer satisfaction, it deserves a customer Freundlichkeits Award!
