Class "Bumber" who is not applying

For my new M8 I needed a certain protection, because I knew from friends that the aluminum unibody is naturally susceptible to scratching. Now I did not want to break anything by any thick protective sleeve the feel of great smartphone. The shell keeps exactly what it promises. There is a rubberized shell, which apply without thick, the surface of the M8 protect and possibly also can alleviate the occasional fall from not too high altitude - without having tried it.
