The protector by itself is pretty good. Have had it for half a day now. Installation was reasonably easy. The film feels like a plastic-PPF(Hydrogel) hybrid. Air bubbles can be easily removed. The size is perfect for the screen. No rainbowing effect on whites. No haziness. S-Pen moves smoothly and there's little to no resistance. When written with S-Pen, indents are not formed, so thumbs up. Price is definitely on the higher side. The only issue I have noticed, is that the protector lifts up from the corners when used with a third party case (Spigen in my case). I have to be really careful every time I remove and put the case again, which I do a lot, so should see how many weeks this screenguard will last. 1 mm reduction on all corners would have made the screenguard case friendly.
