After purchasing the Samsung Galaxy S4 my wife S4 Flip Cover S-View has used. However, this only provides protection against accidental scratching of the screen! Against smaller gaffe provides this no protection, which also was not in the functional specification Developer. For this it is still quite expensive. The PU leather Bluemax book style, however, is stable and practical. Smaller drops are loosely trapped. The Bluemax acts not Globig but really classy! And that for the price! The internal card slot it is better to use for business cards, because I'm not sure if the magnetic closure in credit & Co. the magnetic stripe deletes.
PS: Now I have purchased the Bluemax in black for me!
