Quality, we can succeed in putting the protective film on the first try without bubble. In addition he married well the screen, which is (usually) not the case supplied with protective films hulls.
For those who have trouble putting the covers, I advise them to go and put in a room where dust formation is less risky (kitchen or bathroom for example). To clean the phone screen with a cleaner disposable glasses. And to the film with the help of a credit card when circulates person in the room. (It prevents dust settles during one puts the film).
Voila!
Sincerely,
Avy
