Display is properly cleaned, the film I have aligned and fixed with tape on the short side on the tablet and the carrier film then withdrawn slowly. The whole lasted two minutes and I only had air pockets at the edge, which you can get out easily underline. Now the display reflects not so extreme and the fingerprint is no longer seen that way. The display can be just as operate without foil, no restrictions.
Top product. A bit of tact when affixing the film provided highly recommended.
Addendum on 12:05:15: holds foil is still krälerfrei and no drawbacks in the operation of the display noticeable. Top :)
