However, I had problems when mounting the slides. The whole thing is in my opinion anyway a vexed issue at Nexus 5, because, just when you have the device for a while in use, a lot of fine dust between the display glass and frame collects, the so a film can become a game of patience sticking fast.
The real problem: After I glued the foil to fit, I wanted, really very careful, remove the upper protective layer, but had promptly the film in hand.
Result: a few more, before laboriously remote speck of dust in between.
This is a shame, maybe you could start here and make this upper protective layer slightly less sticky.
Anyway I draw from only one star, as this is also related strongly with the device itself. If not so much dust sitting in the crevices, which can hardly be removed, would you also not between glass and foil.
All in all, the films are their 6 euros but totally worth it if only because of the large supply.
Keep it up!
