The bag is really super. The Xperia M fits in perfectly. It is handy and the workmanship is impeccable. I bought the bag end of February and now has to find the leather is not the cheapest on the bag, but the plastic. The shell or support for the Smartphone is released from the corners on partially. On the right side the corners are from and a crack going from the top to the level of Einschaltknopfes. So it's only a matter of time drops to this part and the Xperia is no longer held. The top left corner is already loose ... so much for durability.
