Although it is easy to place the glass on the screen, as soon as you put it on, the screen quality deteriorates significantly, probably due to the film it has to prevent others from seeing your screen from certain angles. Essentially, when you look at the screen with the glass applied, you see lines (the lines of the film) that create an effect as if you are looking at a 720p screen. Unfortunately, I had not read this anywhere and after doing some research, I found some posts on Reddit talking about this type of glass. Also, it does not do a good job in terms of privacy, as your eyes need to be almost parallel to the screen in order not to see anything (which makes it useless). In terms of quality, it is okay as a glass. Finally, I consider it to be very expensive for 2 pieces of glass.
