Protective shell that I gave my fiancee phone already fallen on floors and tar and not a pet! The hull cash does not score well and compared to shocks. The advantage is that it does not open in two as the Flip Cover and rim protects the screen on a smooth surface.
Only downside is the dust and sand that marks the back of the phone by putting the hull.
I therefore recommend to clean occasionally the hull to avoid surprises when it is removed.
