First I cleaned with screen-cleaning wipes the display, the accompanying handkerchief simply remove any traces of grease, which unfortunately can not be avoided on a touchscreen.
Then should the film to the spotless display. The film has indeed nestled by itself, but not without bubbles. The small enclosed cards you have no chance at the same time to catch all bubbles.
However, I had also recommended no bar as here by a reviewer.
Three points are awarded only because the touch function is really not at all affected and the display also not reflected. Otherwise bothers me every single bubbles enormously and I will look for another slide.
