It is smaller than the mobile screen, which means that there is no 100% protection for the mobile screen.
It is very difficult to apply on the screen. I thoroughly cleaned the screen before applying it, even with adhesive tape (not the small one it contained). Yet, there was a tiny speck of dust that was already stuck on the protective glass. It forced me to remove it twice until I completely removed it from the glass (not from the screen).
The only problem I face is that it detaches from one corner in the phone case, even though there is a distance of about a millimeter between them and they do not make contact, resulting in me constantly having to remove the gap.

Excellent touch feel, fits very well on the mobile screen, does not affect the touch screen, they installed it for me at the store. Recommended.

Before installation, I removed the pre-installed screen protector (adhesive - not tempered glass) and cleaned the screen according to the instructions with the wet cloth. The glass is not easy to install as it does not have a hole for the camera, so you just approximate it with the eye. Fortunately, it comes with adhesive strips that remove dust for small adjustments, but it is difficult to completely avoid particles if you overdo it with the on-off placement. Apart from the difficult installation, it has this black frame around it which has a considerable thickness, resulting in it partially covering the screen if not perfectly placed. I would ultimately prefer a plain transparent glass. Fortunately, it does not affect touch sensitivity. I don't know if it is durable (and I hope I don't find out in a bad way). However, it attracts dust like a magnet.

In general, the glass is good. Although I have put several, it was a bit difficult for me to put it on as I wanted, without bubbles and as best as possible so that you don't notice it. It has a small uncovered margin on the edges that could probably be covered by a case, but it's okay. I declare myself satisfied, especially due to the absence of Spigen glasses, which I highly appreciate.

It seems very high quality, very good application and easy without bubbles, it just doesn't cover 100% of the screen, leaving a little gap on the left and right.
