- Quality of the display may be impaired (that has to do with the function of glare-free, see below)
- Why 3x2 films? It rich 1x2 or 2x2 if you once not perfectly true or has been cleaned.
I opted for glare-free place crystal clear, because I wanted to improve readability outdoors.
Important to know is that this anti-glare foils limit the quality of the display somewhat, as a kind of noise is visible if you look closely (clearly in images, the camera or text on white background).
This has nothing to do with the quality of the film, but with the function (anti-glare).
Who wants to keep pure clear definition of the display, you should prefer to buy the crystal clear sheets.
