It was a little harder to apply than I had expected, but keeping my hands very steady by taking long, slow breaths helped apply it right the first time. I got the impression that if I messed up the first time, there wouldn't be a second chance, so I recommend you take your time. The matte finish is very very nice - it does make the screen lose some of it's crisp-ness, but it's well worth it for the glare reduction and my wife swears by it because it prevents makeup from leaving smudges all over her phone screen. I put this on an iPhone 4S btw and it fit perfectly, so even though it says its for an iPhone 4, it works on both.
The protector material seems to be of good quality. Doesn´t leave sticky residues. I don´t know how well it works on a touch screen ´cos I´m using it on a camera screen. What I can say is you should try this protector if you want to remove glare. You can´t go wrong at $1 :)
