I've used this thing for 3 months now and I'm done with it. The air coming off the top of it hits me right in the neck which is actually not uncomfortable but drastically increases wind noise in my helmet, I can't even hear the music blasting into my ears properly. My Shoei GT Air 2 helmet was actually designed to be exposed to all the forces of the air, which is why some riders who use it with a windshield get weird buffeting, and I have not had a bike with any kind of windscreen for a long time so I'm used to it and like it that way. Maybe next year when I plan on going on my CA to Cape Cod and back ride I'll look at the Madstad adjustable windshield but I kind of doubt it, that thing is just so fugly.
