Especially with touchscreens the burden of films is still relatively large. Here other products had a very short time scratches, or have become detached or could be stick only with bubbles. The films of FoliX are relatively stiff and can thereby even with such a large display, as in the Note II, easily and without wrinkles and with no air bubbles stick (cloth and squeegee - yes so that part is really - is included). Reflections are really well prevented. The presentation is in my opinion only slightly affected. On the contrary, my example appears when eBook reading with Kindle for example the presentation of the text more pleasant.

This perfect power do I rate only with 5-deserved stars.
