Very, very fine. It adapts perfectly to the device even giving him a small look Iphone 5s on the back (see the two smooth bands on either side of a central area more diffuse), it thickens not the Iphone and suggests the metal device ==> one of the covers that alters the least the look of the Iphone. By cons, it unfortunately did not survive the first fall of the appliance; she "sacrificed" for my phone so virtually unscathed. Such bravery justifies that I recommend another in stride ... ;-)
