I just received this protective shell and the only thing I can say is that it is very well finished and perfectly adapted to the S5 mini.
The installation is very simple:
Simply remove the back cover of the phone and install it.
The advantage is that there is no extra thickness.
The texture and the rendering is identical to the original cover. The seal is also present.
The front flap is very classy with inside a soft surface to avoid scratches on the screen.
Perfect product! ... Especially for the price.
