The attachment requires a place without dust in the air, so that no particles get under the sheet.
You must not be glued but holds to a different way unknown to me! Super because so no residue if it must be swapped times remain.
It is precisely for my EOS 650D. The attachment and help prevent air pockets was facilitated by a
Debit card (or something similar).
The film does not fall on and is not noticeable! The touch function is not impaired, and everything works as without foil.
Unfortunately, even the negative things, fingerprints can be seen here as well;)
If the film should scratch it, I'm going to buy this one again!
