I struggled a bit with the installation, although with the help of the SPIGEN case's included guide and after thoroughly cleaning the screen, the glass did not adhere well in the bottom right corner, resulting in a noticeable reflection difference. Pressing the area to make it stick shows that it adheres as long as you press it, but the reflection reappears when it is released. I suspect that compared to the two previous glass protectors from the same company (SPIGEN) that I bought for a high price (20€+), and had no issues with ease of installation and saved my screen from breaking in case of drops, this one does not have a very good adhesive quality to properly adhere to the phone screen.

Also, for those who mention the black borders on the sides, it is true that they hide about 20% of possible text when the screen is filled (e.g., in the browser's read mode), but it is not of great importance. It becomes less noticeable after some use.

As for durability, only time will tell because I just installed it, although it seems quite thin and lightweight compared to the two expensive ones I mentioned earlier. We shall see...

It does not affect the handling or the image, but it has a black border on the edges and covers a minimal part of the screen.
