I have the cell phone pocket for several months now in use and am very happy with it. The case provides good protection and the cleaning function is also OK. While not as thoroughly as if you polish the smartphone itself with a cloth to a high gloss, but "once over it wipe" - more, it's not when the device once again pure and pushes out - very neat. I renounce any case since a screen protector.
In order for the cleaning work has to sit close the shell of course. The smartphone slips accordingly not just pure and back out, but you have already with a little "emphasis" raus and reinsert ("it's not a bug, it's a feature").
In the meantime, there is the model also still in Alcantara. Probably looks much more stylish, but is also more expensive.
