The ATIV S can be precisely clipped into the cup, where it holds very well. This is genuine leather and the case therefore also looks very nice. The two long sides of the handsets are not being protected is clearly visible on the product photo and I do not's criticisms. But I can not be more than one star at best will give, because the top of the sleeve is strongly arched, a gap of 3 to 4 mm is to display, say, the top does not lie flat. Added to this is that the magnetic closure is very weak and the flap with the integrated metal piece survives anyway and therefore because of this whole construction, the top of the casing is either partially released from the magnet and is open, moves to the side, or moves upward so that additionally added to the already existing vault a few mm. The display is thus extremely poorly protected. And by the curvature also suffers the appearance of the envelope extreme.
Update of 13 May 2015: Mumbi has sent me a free replacement. Excellent costumer service !!!! In this second case no bulge is present and also the tongue of the magnetic closure is not so far above as in the first delivery. A small gap is created mostly still as the slightly protruding flap lid moves up, depending on the storage location (backpack, bag, etc.). My new Conclusion: Case 4 stars, 5 stars customer service with Plus. Thus rounded 5 star.
