A protective film, if it is not perfectly clean, leaves tiny bubbles on your screen to the application. It just spoils the fun. Yet the films seem well conditioned and 'take off' of a surface conditioning just before installation. I spent 3 before only obtain one 'small dust'. The best is the enemy of good, I have not tried my luck with the remaining 3.
Little dust found on every shield. No way to set up little Avoiding bubbles. 3 out of 6 tried before finding one with only one piece of dust. Did not try my luck on the left 3.
