Appearance and quality of the cover are very good, in that it is relatively thick and is easy on the edge of the display, you should also protect your phone well from a fall. For me it is still not usable, since images are exposed totally blurred and strange flash. The G3 has indeed a final flash, which side is lit by the shell into the lens. Twice the same image in darkness, one with and one without a cover illustrates this in a reproducible manner. I'll still keep them at least at festivals or similar To use.
