The attachment is simple - there are in addition to the three films, a mini-blade, a microfiber cloth and a German, good and illustrated instructions included.
On both devices me a completely dust and bubble-free adhesion problems was possible.
The notice described in the manual that you can (or similar eg scotch tape) with a piece of tape during application of the film to easily remove dust particles, has proven to be very practical and useful.
The presentation of the display is - as with all anti-reflective display films - a little pixelated, due to the rough surface of the film. However one gains a really extreme reflex liberated view of the display, which makes viewing possible even in sunlight.
The product I can, after several weeks of use, fully recommend and would buy it again at any time!
