The attachment was a bit annoying, maybe you do that better as a couple.
I have not quite perfect hinbekommen (1mm offset and a small bubble), but much better for the first attempt than I thought. Bubbles could be gradually push out and it sticks really well.
Touch (and pin contact) works fine as before and I can not detect any color distortion / blur etc..
The surface can now be even easier to clean than the originals.
It is not quite as smooth as glass, but even I find ok.
Very nice also that the same 2 films in the package.
I can only recommend and hope that they can be detached without residue again.
