The protective film is very good and relatively easy and bubble-free installation when one considers a few things. In any case, you should take a little time for attaching the foil. In addition, you should really clean the display seeehr well and pay attention to a dust free environment. I have also used the already repeatedly described "trick" with the scotch tape strips! It worked great. The resulting bubbles with me I can cross out to the side with a normal debit card. The film was absolutely perfect fit for me. I recommend this product !! more Still on the edge: fingerprints can be seen, of course, still on the display, but the film is supposed to protect only the display from possible scratches .... from time to cleanse the display is now being expected no problem .....
