While quality level, we feel that it is a true Samsung, the phone is well protected. It fits in perfectly and one could almost think that the hull is part of such, so it is cut to the hair, so for this: 5 stars. BUT: by cons, it completely distorts the phone design, wholesale, it makes ugly as hell. At the same time, it is a protective shell, so .... Advisory amateur design S4: go your way, the other, go, of course!
