Caution scratches

I am generally satisfied with the protective film. The tablet is well protected, but also a bit heavier.
However, the application of a protective film is recommended on the display. Because (which has Dämel Whatever made the branding) is a small metal clip with the IVSO lettering attached to the lid. Metal and glass makes really nothing, since the metal is worked smoothly and well on the contact surface. However me somewhere seemingly a crumb (or a grain of sand) has come between glass and metal. The result is a "scratch circle" since where the envelope lay on the display and has worked in transportation with the movement ...
Very annoying when a new tablet and especially since I've really taken that no dirt comes to the display, probably not to be avoided for duration.
Result: Now have attached a protector.
