After I'm almost always desperate when applying common films and had to constantly fight with bubbles, I discovered more or less by chance this protection glass. Intrigued, I ordered it ... and was not only surprised but thrilled. It is recommended, however, that you really are when applied in a dust-free environment and also cleans the screen well in advance. If one of the glass, it soaks up the display to normal. But you should really hang it until you are really sure that it "lands" on the right place. This should be done in peace and without hassle. A correction is in fact almost impossible, because you take the glass again from the display, it pulls on the adhesive side like a magnet to dust.
Although the attachment requires a steady hand and a lot of precision, but you will be rewarded with a bubble-free protected display, which also seems clear and that is not only protected from external influences, but also surprisingly resistant to dirt and fingerprints.
