Once in place the protection is practically invisible, no opacity noted. At the touch it is really good, similar to what may propose original screen. What about the sensitivity and responsiveness of the screen? I havent noticed any difference. The screen is still as responsive as well to finger quavec the S-Pen.
In the end I'm really convinced this is a high-end Screen Protector far superior to plastic protections "classic". The only question I ask myself, this is how long it will take. That's what will define, for me, its price / quality ratio.
