Advantages: the look, to love. Being such soft rubber = it does not slip on a table or a smooth surface.
Protects fairly well, and its thickness allows to put the phone face against the table without touching the screen.
Disadvantages: Like all the shells that do not include the screen, I put a plastic film over and hull sometimes raises the edges of the plastic film thus "it is tack free" in some places.
Hard to get out of the pocket quickly if needed to answer a call, hands full :)
And I'm afraid it does not wear with time, but for now it's fine.
In the end, "it changes a little" and for the price it's just as well ...
