The battery cover has a very good fit and looks from the back of a lot better than the original, above all, he is absolutely resistant to fingerprints. But by the side, about 2.5mm thick chrome frame the Mega looks much thicker than the original frame and is also "edged" in hand - but that depends on your preference. The really big problem of the lid is however the significant deterioration in the quality of reception (WLAN and GSM) - in both variants my Galaxy shows an approximately 2-3 bar lower rash in the signal strength indicator as to the original cover. For me, ultimately the reason again to use the original cover! For the optics, I would assign 4 points, for the (limited) function but unfortunately 0 points.
