I now have a few days are the protective covering of Mumbi for the Sony Xperia Z. I knew the type of protective sheath nor of my Samsung Galaxy Express. There she has always given me good service. The protective cover for the Xperia Z is similar but much thinner and a bit softer and flexiebler! The protective sheath can be easily installed on the Sony Xperia and surrounds the smartphone well at the edges. The Access to all ports are available and easily accessible. At the points where the gaps are, the margins are pretty thin and flabby. To this end, there is a star deduction. Otherwise, it protects my smartphone as it should be. In addition, I have a contactor each film to the back of the smartphone and a screen protector, also of Mumbi, attached. With my old cell phone (Samsung Galaxy Express) it has thus brought good protection, it still looks like new today!
