Sunday evening ordered and delivered Tuesday morning. Did the shell of an Xperia Z1 ordered compact and it fits properly. The processing is also good (no sharp or protruding edges). I can not confirm that the locations at which the sheath covers the outer buttons of the mobile phone, would be too hard also. Everything works great and you should not press with excessive force to the shell, to activate the buttons underneath.
It should here be noted that I have the envelope only since about a week. I can not say anything to longevity or durability so here. But the relation of price, quality and delivery time until now I give without feeling guilty 5 Stars.
