The envelope arrived today and makes a great impression. She smells neutral and does not stink. It is made of elastic silicone and encloses the back cover and the sensitive edge of the Galaxy S4. All major key and interchanges are cut, so it's easy despite envelope this to operate. The original charger fits easily. I also like the sheath on the edge is higher than the screen, so that a lower splitter probability arises, the smartphone should even fall. I especially like also the simple matte black design and the beautiful lettering! All in all a highly recommended product!
UPDATE 04/24/14: Unfortunately slowly disappear the writing ... Nevertheless, I find the shell highly recommended. Nevertheless: 1 star deduction.
