Now I also had the opportunity to test these cases by Spigen. The all-round, separate plastic ring it acts on the one hand very noble, on the other hand strengthens the seat and stabilizes the whole. I have in fact the impression that the S6 is now very well protected.
However, the smartphone magnified by the enormous shell and almost reached the level of a Galaxy Note. The unit also works by not as narrow as it is actually - on the contrary: It seems downright clumsy. The Mumbi case, however, is downright dainty.
The cover fits very tightly, making it a bit difficult to install. It is best to only draws on the silicone sleeve and then brings on the plastic ring.
Incidentally, the inductive charging also works in conjunction with the sheath.
