Expensive but very worthwhile investment

I take this film or this glass for my Z1 Compact. The price is, compared with conventional films, not just affordable, but one must consider that it is here more for a glass. Some complain here that it is difficult to mount it. This I do not, because if you're vorsichig and takes some time, it's easy: Smartphone screen with a clean microfibre cloth (preferably moisten slightly beforehand), remove foil, easily put the glass on the display, adjust and Tap once with your finger in the middle. The glass then sucks itself firmly as if by magic on the screen of your smartphone without bubbles. At most at the edges you have to help out again after a few minutes, in which one wipes over it with the microfiber cloth with light pressure - that's it. The phone is then only slightly thicker, but very well protected against scratches. I think the feeling of this glass even slightly better than the original underneath. You can go with a knife or sandpaper it and nothing happens. The phone looks always like new. Very recommendable!
