I have to say, now I know why the costs more:
1. My touch screen responds much better than before with the NoName, as if it does not slide!
2. despite the fact that Sony's film to a thicker and probably more robust!
3. Very easy to apply, who since reinbekommt bubbles must be extremely do wrong!
4. If my NoName film was not cut from the display light sensor, here already, so no more corruption.
Watching one must, however, also here, that's no dust underneath, so before display (better all Nex wg.evtl. Static) liberate very thorough about it.
How scratch-resistant or sensitive it is ultimately must first rausstellen yet.
