miserable because hardly usable

I can only say: Stay away from this film.
Despite repeated attempts, it is neither me nor others have succeeded without air bubbles to attach the film to the Kindle Touch. We were probably just too stupid to!
Neither debit card nor the removal of the film have helped, especially as the film quickly after peeling has fluff on the adhesive surface. And who has already made available to apply a clean room, the film?

Addendum:
the company has called me, sent and then asked me to reconsider the free replacement negative rating.
