The case fits absolutely perfectly to the S4. On the long side there sitting by the hardcase absolutely perfect and tight. The softcase is soft enough to reinzubekommen the S4 comfortable but rigid enough that it is not bends up on the short side and still get dust and dirt between the casing and mobile phone. The processing is, as I'm already used to it from other Spigen cases, absolutely high quality and robust.
The only drawback: after a short time are slight scratches on the back, as just every bit of dirt around the slide of the phone on the table, for example, also on the back scratching. Unfortunately, this is painted, so you can see clearly even scratches. Although I did not expect that, there are still only 4 stars because the one by normal plastic, not painted, could easily circumvent.
