Since the S5 itself is classified as waterproof, it makes little sense, even an extra waterproof case for buying, unless one really wants to go diving with it.
The use of an induction charger is possible with the case even without problems.
With regard to the impact protection, there is plenty of Youtube videos, it is only so much said: Who else gets broken his cell despite this envelope, which must act already wantonly. Falls from 2 m height and more able to absorb the Case.
Strong buy recommendation
