Although this Iphone loses again its thinness, but in my opinion very well protected. By Sleeve for iPhone is about as thick as a S4 with silicone sleeve.
Anyone who wants to get the slenderness of the iPhone upright, this envelope should not buy, but switch to a silicone shell (Here there is also a very thin shell of Spigen, but not such a protection offers like this one).
I'll stay with you, because it is next to the top good looks easy. The local knobs aluminum look fabulous and work really well. Through the rubber while the connectors are somewhat lower, but that's my view no problem. The charging cable goes in with no problems.
The only thing missing here is next to the black rubber, even to make a white rubber, but the color is merely a matter of taste.
