Contrary to what some of the negative reviews here, it was not difficult for me to put the films on the displays. The "Aufklebevorgang" is certainly not for 4.5 or 6-year-old children, but with a steady hand and a bit of concentration, it is no problem to achieve bubble-free results even the first time. By the way the included cleaning cloth was a great help, after the cleaning process (which should be carried out necessarily before attaching!) Were the two screens cleaner than they were when delivered.
The writing experience with the stylus has really improved, even if it was already well in advance, of course. Nevertheless, one feels with protective film somehow safer, even in the wildest pen actions that yes absolutely requires the one or other game.
All in all I can give in all respects as a conclusion really just "very good" and so 5 stars. We can only hope that the films also are durable, but the first impression suggests also here on high-quality material.
