Where to start... firstly, the packaging provides very useful accessories for the installation of the glass... it has detailed instructions, the appropriate cloth, and the appropriate "tool" to remove any bubbles that may occur... quality A, good protection, you feel like you haven't even put on a glass... simply the best... when I need a glass again in the future, I will only look for Spigen!!!

Excellent touch sensation, almost as if there is no screen protector applied.
The installation is very easy and does not require experience.
The colors and brightness were not affected at all.
The only negative is that it leaves a gap at the edges of the screen, but in combination with a case, I think it provides sufficient protection.
