The only (small) negative points are:
-The Rubber is relatively stable, but I am afraid that it does not hold too long at the edges.
-When Delivery are on the insides of the edge mold lines. This should remove necessarily to (facing to protect the envelope yes) prevent scratches.
Overall, a great shell that served its purpose, while is slim and looks good.
UPDATE 08/01/12 ---------------------------
Had the envelope for some time now. Already after three weeks began the top layer of rubber to break away in some places.
Particularly negative, however it should be noted that the envelope a piece of the cell phone can be up and down freely. So it happened to me that the SGSIII already at a slight fall fell on one of the exposed edges and already had a crack in the glass of the screen. That the Galaxy S3 is particularly susceptible to such damage is related to the type in which the glass is a tiny bit thicker than the rest of the device. However, a shell should also protect against drops and certainly does not have this. Personally, I have now ordered a silicone sleeve. Although are much thicker, protect the phone but also against all damage.
So if you want real protection, which should take another envelope. But if you want to keep only the high gloss back from scratches, is advised very good and cheap with this dish.
