The product description says "a clear shell shiny crystal case ..." Therefore we expect a completely transparent shell, type "crystal" but in fact it is a silicone shell "translucent": it has a appearance slightly "frosted glass". However, once mounted it allows to clearly see the back, the logo and details of the phone, so it goes, but it's not "crystal", you must know if you insist. Apart from that, the hull is well on the phone, all openings are positioned, the touch is soft and it does not slip from the hands. A small note: other silicone shells that I, the buttons "power" and "volume" are not exposed to air but hidden under the silicone, it is indicated by a "wrong button" engraved on the hull. This allows you to manipulate while protecting them from wear because they are very used buttons. On this shell, their location is cut and they are apparent. So they suffer wear induced by the touch of your fingers, I think it's worse.
Regarding protects screen I have not asked but seems standard quality, cut it right to size the GS3, without overflowing on the side of the screen bulges.
