So I flipped around a bit and was able to find here. The delivery of the films were Ruck Zuck.
Unfortunately I had to order several Kindl Paperwhite because errors still occurred (halos, wrong built-in display ..) In this respect, I was glad in the parcels were a total of 4 films.
The film itself is very easy to apply. To get it free of bubbles, you can make do with a credit card.
However, I found that she was not always a perfect fit. So I had to twice cut the film slightly shorter.
It may be of course that this was not because of the film, but at Kindl himself as possibly the display sizes are not always exactly the same ... but it could also be due to the film ...
Anyway, I tried again to reuse the film during replacement, but this did not work out because then formed small dust inclusions, which led again to mini bubbles on the screen, which could not be "crossed out" with the credit card ,
The film is therefore intended more for "single use", but also does not matter, since 4 are in the package.
It sticks well and keeps such bomb. One can well over it swipe and the device responds exactly as if no film would be on it. Also not reflected in reading.
For me, therefore, highly recommended !! ---
