2. Very few of the films to which these unfortunately are, have only a protective layer on the inner side have - the minimum program. I'm used to that films are supplied with three layers; one to protect the upper surface (might have been a good idea in view of the fact that such tours mentioned, one of the three films already came with me with scratches on the upper side), then the actual, adhesive film and including, of course, the severing, lower layer.
3. The application of the film also turns out to be very difficult because it is not clear which of the two layers, the actual film and which is only the lower protective layer. Therefore it is necessary before attaching the film already open a piece in order to ensure at all, that applying the right page. This time is already programmed that exactly at this moment already gets dust under the film. Competitors solve this problem with a first, numbering and secondly a visual guide. This is absolutely essential, because the application of the film must be a fairly quick process, if you want a bubble-free and dust-free result. One should clean the screen with a cloth, and as quickly as possible pull the film about it before dust flying through the air, in between sets.
Yes, a visual guide is available, it shows me only that I have to firstly clean the display, secondly dissolve the protective layer of the film, the film is to raise third and fourth, the bubbles will underline with a card. Wow, that is not particularly helpful that. A drawing showing clearly which of the two layers, the actual film and which is only the protective layer would have been helpful, but does not exist.
My expectations I get for absolutely appropriate after these films are among the most expensive, you can buy. Even in local commerce I have already bought much cheaper films that hit this slide set in all respects. And it's not as if this is my first film; I have collected quite a lot of experience and had wonderful films that I could absolutely raise dust and bubble free.
To be fair, be it positive mentions that at least one of the high end, the microfiber variants.
A second star there is because I could muster neither at all eligible films adequately and therefore can not judge how it looks and if, for example, the pen may well slide over. In case of doubt for the accused.
