So I had a week with it installed and it absolutely deflects a lot of the wind to the chest, but yes Geoff, agreed, it is all at the shoulders and head. In a crouch though it is beautiful. Wind right over my lid.
The light reflecting is still bad, though not nearly as bad as as if I didn't paint it. I still get the reflection from on the matte black, and it does transfer up to the unpainted section, but there isn't any glare. It as absolutely bearable at night, and actually now that I am used to it, I pay no attention to it. I also taped off the DRL behind the screen like Geoff did. That helped a lot more.
You would think the manufacturers would design a bit better to help eliminate the glare behind the shield. I understand though that extending it lower probably helps a lot with wind flow around the rider and catches the wind at the right angle.....at least I hope they tested for this!
Keep the rubber side down!
