Supplied gets you two screen films - one is probably intended for testing and learning; Nevertheless, I managed to get the same from the first slide to success.
It is important to work in a dust-free environment. In addition, you have the very narrow margin exactly straight start (100% - not 99%!), Otherwise the film (11.6-inch display) then sits on the enormous screen width completely wrong!
One should have no qualms against the foil deduct repeatedly and new should be recognized in each speck of dust, in every little bubble, or even if the film is crooked.
It took me about 20 tries before the sheet of dust and bubbles and sat perfectly straight. And I had to repeatedly statically attracted dust grains with a fingernail from the underside of the film scratching - no problem. The included sturdy spatula pushes when pulling inched out any possible air bubbles.
And finally she was correct, and the anti-glare display now looks as if it had never mirrored.
What you have to then live: the one-handed or Sticky Keys (on a tablet stand) does not work properly: the film apparently isolated little too strong, so you have the second hand still on the metal housing of the tablet when using the touch screens needs, then that's no problem.
