Installation is easy. The frame guide didn't help much. I tried to use it but the screen doesn't look centered so I had to redo the ink install. There were blisters, but they disappeared after I stroked them outwards several times. As for the feel, it feels so smooth. Not what I'm looking for in terms of matte finish. There is no grip at all and it doesn't feel like paper. The optics and viewing angles are good, since it is a kind of hybrid of transparent and matte, the screen does not appear washed out. As for the quality of tempered glass, I hope it protects the screen from breaking like any other tempered glass. Will I recommend it? It depends what you are looking for. If you're looking for something that offers extra protection without sacrificing much of the color washout then I would recommend this product, but if you're looking for that paper-like roughness I won't. I might consider other products because I have a hard time drawing on this one as there is no support at all.
