The following steps I have performed:
one of the three films concocted ==> that is, time-oriented which are 1 and 2 (the protectors of the protective film ;-)).
the iPad mini released on the packaging film
Protector 1 peeled and placed the film on iPad. I tried to align the film on the big hole (recess for the iPad button). Thereafter, the film possible rounding off on the iPad glass muster (so has to be less bubbles).
the isolated bubbles I then weggestreift with your fingernail to bark out.
Protector 2 peeled and ready!
With regard to the operation of the iPad with the film, I can only report positive. If you do not know it that a film is above, it falls (neither optical nor to use) one not to.
Conclusion: Great film (s) at a good price. Absolute buy recommendation.
