The iProtect protective case is made of soft silicone, number of holes agrees with the Apple product match.
Perfect fit is also buttons function (though the buttons, which are covered by the sheath, need a bit more pressure, because that material is soft).
The product picture is misleading, contrary to the picture is on the front page no thin strip in the color of the cover iPhone5c seen. The rim of the shell is much thicker than the original.
One disadvantage is that, however, because the original is quite hard and I am convinced that in case of a fall, the soft iProtect product absorbs the impact energy better.
This also applies to the more pronounced bulge on the front side. In addition, the display glass is a little further away from a surface when you put the unit on the display (which I always do, because it may concern other nothing that my contacts so via Whatsapp, FB, etc. tell).
What bothers me personally something (really just a smidgen, not a reason to buy renunciation) is the small distance of the rim down to the home button. But clearly: either thicker edge for better protection or thin as the Apple product and anxiety around display. Mir is because of the thick edge prefer.
