By the way it is, depending on your hand size at first take some getting used to typing with the device in your pocket. Simply folds only on the front, this bothers on the left, which is why I'm gone over for real letter to rotate the flap on the back. Of course, the handle is also so strange at first, because the whole thing is so slightly thicker, but not really disturbing.
In another vote is indeed a Velcro talk (even for the same model), but my bag has a magnetic closure. In itself, this keeps the bag closed and reliable, easy push sideways on the flap in the closed position but ensures that the tab can be rotated slightly, making the magnets no longer rest on one another and the tab on the principle of self-will. Say, the area covered by the magnets is not very big and the magnets also not very strong. The extent to which, in a case could potentially be a problem, I had not yet been observed.
In general, the phone is "overlap" in the pocket to be everywhere, but has to be clearly stated that, for example. A steep fall would definitely lead to the front to the fact that the flap moves and make a part of the mobile frame contact with the ground would. Together with the potentially weak closure is thus not guaranteed that the unit a case really is completely undamaged, even if a case should rather be on the back or a flat case to the front no problem.
The onset of mobile phones is very simple, it has to reingeschoben only on the Flap side and then the left "purely folded". Accordingly, it can be exempted by a light train also links back from the lock, and then take out. Since here but not much force is needed, which could in a case with an open pocket also become a problem, because the device might then eventually released from its bracket.
It should also be noted that recognized two card pockets and one large compartment are as in the figure below in the side flaps.
A note that affects at least buyers of Z3 Compact: At all relevant openings (except for the SIM card compartment to which you anyway rather not want) in the bag free and accessible. However, the tab overlaps the power button and the volume buttons, that is, without the flap to open, for example, no volume control when listening to music possible. Here, however, affects the weak closure helpful because it so relatively easy to open the flap briefly pressing the keys and then close again.
Conclusion: For the price, the bag is in order, however, offers no protection foreseeable in all situations. So who primarily examined the case as a protective measure, should still look for alternatives. Who can with the knowledge that the device may still captures despite bag scratches, live and eventually the "extras" such as the card slots needs or who likes the bag simply, can be accessed here.
