Unfortunately, the films were not exactly

Why only 2 stars? Quite simply ... protective films for displays should be very accurate in my opinion, in terms of fit. This was not the case for the two films. The films were at the edges approximately 1/2 mm too small. These tiny areas was formed dirt of impaired functionality. By cleaning the film finally peeled off. Even
Hip caution when installing, the one should have to peel off the film again, it is almost no longer possible to install it without air bubbles. In principle, a great thing, but under such circumstances, very annoying. Have a specialist leave a protective film attaching, which was more expensive, but Frustfrei doing their service.
