Having eaten some other protectors have been glued to the display, so I have to compare it to.
FoliX are by far the best!
Before gluing you should first of all, the film loosely based on the display put on to get your bearings as you want to align.
The delivery is very good, soft cloth.
With this, the display should be clean, be cleaned of grease and lint.
Perfectionists I would use a Dusters recommend (there's also Amazon) to also remove the smallest Staubfussel.
Then fit the new film fit and press into the center outwards (with the supplied cards).
Due to the fixed properties of the film it is hardly possible that bubbles form.
Then rinse with the soft cloth and you see nothing from the fact that a protective sheet is glued.
Absolute recommendation from me, better It's really hard (a bit of skill course required)!
