When I got the delivery, I first thought that either it was wrong, or maybe I ordered the wrong item. I had since in de hand a glass, not a film. I was curious how that should work. I made the display of my Grade 3 thoroughly clean and the protective film from one side (to be placed on the display) deducted the disc and I already had the wow factor. The adhesive disc like a magnet without bubble - nothing. Then came the next surprise - the touch-sensitivity. The display is as touch-sensitive as original without protection. The smartphone is a few times fallen down since I have the protective shield on it - nothing happened. I can recommend it only. It's like a second Gorilla Glass and as we all know, better safe than.
