Tacky feel absolutely great-looking buttons, nice idea with the "staircase" or the distance between the lip to the screen (so the display film can be guaranteed not raised), very unobtrusive "welds".
In the rear / front Seitenfuge (the mobile phone completely bypasses) of the case is made up like dirt from the fugue, however, so wide that you walk in well with a microfiber cloth.
The case is also easy to keep clean and can be quickly and completely by all "fat fingers" free with a slightly damp cloth and then still beautiful matt.
Absolute buy recommendation.
Update 28/11/2014: The Case begins now to lose at one point on his coat and then there seems by shiny plastic. After two months of use (the road only with bag) with cleaning up the cases all two / three days by free layering wipe with a soft microfibre cloth is unlikely to happen.
