As an exercise, I first started with the small, upper display: Thoroughly clean and wipe dry, the Red marked, remove protective backing sheet, aim and press down - that's it!
Sass right the first time, then still remove the top blue foil and the glass firmly and immovably seated on the small display of the 7D!
The same procedure for large main display: clean, dry, air stopping! and protective glass press of the long side of at the screen! Top! No annoying bubbles like a foil - simply good!
Well, the glass has a few hundredths mm thickness and is slightly raised to perceive on the camera back, but you have to look very closely to even recognize a screen protector!
For ease of installation and the good quality material there for me 5 *****
