The fact that I mention that the manual is not in German, should be interpreted to the effect in this case, that it is so simple that no guidance is needed. Simply the phone at the upper edge of soft start, press briefly to finish. And already sits the Samsung Galaxy S5 exact fit in a hard shell, the upper corners / margins (the facing the display) are softer and thus kept a little more flexible. This also makes for a nice optical dichroism. Overall kept very thin, so my bag bulges out not in addition. The protective cover is for very stable, my first test was of 2.20 meters cast on stone floor (but without cell phone in it ...). No scratches, no dent. My second attempt was striking on a table edge (with mobile phone). All good.
