When it is time attached ... top

First of all,
the manual is really rotten.
Based on the pictures and the experience with screen protectors, we have it then but still managed. Well, almost.
Near the edge of a Mini-Mote has crept. And since the difference to the film is observed.
In a film that is inherently flexible, so a grain of dust is of no consequence. In the hard glass pane, the protection trips repeatedly over a large area around the "defect". So settle screen protector again. Not so easy the entire disc needs to be replaced wary of a 0.3mm thick glass pane, as you can not simply resolve the corner and pull off the area until the dust particle ... because.
If the protective glass but then once seated neat, dust-free, it is virtually no longer be seen and felt.
The resistance to fingerprints is really top.
