The touch of the screen does not create a problem and seems durable, but to install it, you need to be professionals with many years of experience in glass installation, and even then, if you succeed. The glass does not have glue on it, but rather in a pen that you drop drop by drop onto the screen; then you place the glass, wait until it comes out from all sides of the screen, and then for 30 seconds, you shine the screen with a UV lamp that is included to dry it. Be careful, if you drop a little glue, the glass will not stick and will be ruined; if you drop too much glue, a lot will come out around the screen and will stick to speakers, paddles, etc. If it falls into the phone case, it will destroy it. Also, the curves on the right and left are impossible to stick because they do not fit properly on the curves of the screen.
