Bubble-free? almost impossible

The film itself is perfectly and protects your device perfectly. However, the bladder and above all dust-free attachment is a real pain, unless you have the possibility of applying the film in a dust-free environment. The finest dust particles generate unfortunately small bubbles that might not be noticeable to other devices on a Kindle on which you indeed want to read some for hours, but work really disturbing.
I gave up after several unsuccessful attempts to dispose of the film and am perfectly happy with my Kindle Touch again naked. Until there is a film that is really easy to assemble without bubbles, I will certainly put your fingers on diagnosing and treating the Kindle so carefully that a film is not necessary.
Edit: I have decided to award a star more because my very accommodating a new film was sent after I described the problems with the first. The seller is very responsive, polite and easy to complaints. I have also been more tips for attaching the foil supplied, for example that a well-damped bathroom is dust-free. Still does not change the fundamental problem: without bubbles I can not get it back, and that affects the reading pleasure unfortunately considerably.
