The cover fits perfectly on smartphone, so does not wobble and has no sharp edges. Each port can be reached effortlessly. The volume / Power buttons function properly. They have some play and wobble thereby partially but not audible
The protection of this envelope is absolutely trustworthy. Here I am not afraid, if my smartphone should sometimes slip out of his hands. On the sides of the phone is a total of 5 mm (measured it) thick. Here, the Nexus is also square, whereby operation is made more difficult (one can imagine an oversized current iPhone). For this purpose, however, please read the hint!
Personally, I'd still want another variant of this sheath in a thinner design, as this design is unbeatable in my opinion.
General information regarding cases.:
Of course, smartphones are a little thicker by such cases, which should protect your smartphone else also? Here you can often tell the thicker, more protective (in case of a fall). Thus, every man for himself must find a compromise between feel and protection.
