Delivered, unpacked, amazed.
The cover fits perfectly, it has for the volume and on / off switch again keys over it above the original key and all work well. The only slight criticism that one could install is that the mute button is relatively low, so maybe not everyone easily rankommt with his thumb and instead must take a smaller finger. For me, this is not a problem, but rather an advantage, because you thus prevents you accidentally mute the phone, as it's also happened to me with my old iPhone 4S again.
Conclusion: with temporary it is nothing, I am so pleased that this envelope my remains permanent. :-)
