The assembly proved to be not easy. To make it short, I needed all 3 films a properly positioned hinzubekommen. And although I would see myself as an experienced user of the attachment. Why was the Assembly challenging? Now I would say, because the film has only about 1 mm spacing in latitude and longitude to the screen area of the Kindle HDX 7. Thus, the first two films went on it for, because I do not hinbekam it is indeed the first time, to position 100%. Ultimately, the result was that the film on the edge of decency something and then of course trained bubbles. If you remove a sheet and retried aufzusetzten has usually a few specks of dust under it, which is not my claim. This then has the first two films killed. Therefore, there is an average rating from me. When the film was slightly smaller, then they could be applied more easily. And from my feeling that would bring the look and feel no Abruch because the edge of the Kindle Fire HDX's wide enough ;-)
