That visor has completely saved my face.
I clipped my nose (I was snowboarding) on a single barrel rail on a stairset. Got flipped over and ended up gutting the rail. My momentum carried my head over and into the steps on the other side of the rail. I couldn't get my hands down, and went face first. I felt the visor hit the stairs, and could feel the entire helmet flex. I ended up perfectly fine, without a single scratch on my face. Without that little visor, it would have been a pretty nasty injury.
