I have the screen protector me - bulletproof glass for Sony Xperia Z3, the same for the front and back ordered. The film was very easy to install. No bubbles or whatever. The glass film does not impede the operation and not the image quality. The display is not covered at 100%, but that does not bother me. There remains approximately 0.5 mm free at the edge. Or protection, or scratches on the device! Even my scratch test has passed this product. I'm very satisfied and would recommend this purchase.
