Then I noticed that the plugs on the Xperia Z1 are quite delicate, so you do not want to remove a day to load only to the mobile phone. In the dark, it is a real challenge. So I borrowed the magnetic charger: buy [[ASIN B00H2EEB4S]]. That does not fit to the Mumbi case. Therefore I have brought me this envelope here.
Compared to the Mumbi shell is much more freely from the mobile phone. This facilitates one hand operation, because pressing directly on buttons, having to press instead of the silicone. On the other hand the protection factor significantly (!) Less. I doubt that the shell can protect the screen from a fall on the front. Up and down is no protection and the side slides the hardcase easy way. My simple test: You put the phone on its "face" and pushes from behind it. Touches the screen the table, I'm assuming that it strikes even in a fall. At Mumbi the display remains always protected by a silicone bead at PhoneNatic it touches with the slightest pressure the table.
Now comes the biggest annoyance for me: the magnetic charging cable does not fit. The recess for the magnetic connection is considerably smaller than that for the SIM and Micro-SD card. I can neither PhoneNatic nor the manufacturer of the charging cable chalk because both is not a genuine Sony accessories. But it is annoying for me anyway. Because I would have to take at a return at 4 declared value for 2x2 delivery costs I decided to grab the file and resolve the problem yourself. Lo and behold, the magnetic cable fits.
Conclusion:
Who does not use the magnetic cable, and attaches great importance to high protection factor, should resort to Mumbi case.
Visually, the Hard Case is tattered look after a few weeks, because the rubber coating dissolves. Among then is smooth plastic.
Who wants to see a little more from the phone, and the less a person accepts protection factor, can take this hardcase.
Anyone wishing to use a magnetic charging cable, must play around until it finds a matching combination of Bumper case and cable. ... Or access to the file and to carve the matching holes itself.
