The glass is fine and clear as spring water. The brightness is not impaired. Orzly provides the alcohol wipes and after installation as well as full documentation.

But the SAV Orzly was on top despite communication difficulties due to too great restrictions that Amazon needed to exchange messages between client and external vendors. A reproach anyway, the Z3 Compact, pregnant are not surrounded as suggested by the images. But protection is none the less complete.
