In the packaging I found the case to be, a protector, a little microfiber cloth to clean the screen, a plastic card for smearing the air bubbles and a concise guide.
The film is perfectly cut. Not too big to look over the edge, but not too small. It consists of 3 parts. An upper layer (which protects the spreading of bubbles from scratches), the adhesive display sheet and a carrier sheet, which is removed as the very first thing.
The application went pretty well. The display no bubble can be seen.
For the actual envelope: Even when you insert your smartphone you can feel that it is quality. It's surprisingly strict. When you insert the last corner "snaps" of plastic to formally.
Unlike other cases, the material is to not so easy when you playing around with your fingers in mind.
All entrances to the smartphone are easily accessible. The Sound Rocker works as well as the power button, properly. Also, the pin can be removed still easy. The USB port is freely accessible.
The camera is different from non-enveloped, encased by a few millimeters of plastic and thus perfectly protected.
I have not tried it yet (and I do not plan to), but am sure that this kind of case, thanks to the soft lining, can withstand a lot of falls. Very robust, very reassuring!
The only negative aspect is more than that the feet on which rests the shell, still tend to be slightly non-slip.
That said, I do not see no reason to buy the envelope a second time.
Whoever stands on this design gets an envelope which makes the smartphone a lot more robust against external influences.
Full 5 of 5 stars.
