The shell is very strong, similar to the original Bumper from Apple. However, here the reverse is also fully protected.
It can be difficult to draw on the iPhone, but it indicates the exact seat. Despite everything, thus sees the iPhone from not pretty much broader. It also nothing slips.
All slots are cut large enough for me fits an alternative headset without any problems.
The phonetic / Quiet buttons can still be good and operate without much effort.
Due to the different materials at the back (top transparent polycarbonate hard, scratch-resistant and soft bottom) iPhone not quite just lying on a table. But that does not really bother.
I am thrilled to have almost half paid less than in the consumer electronics store and can only recommend this envelope. With a proper screen protector iPhone is perfectly protected.
