Ok, just back from a blast with the new Ermax screen.
Short and sweet review.... Had it set to lowest height, and I am 5'11". It really is way better at deflecting the air, hardly any buffeting compared to the standard screen and when I ducked my head slightly, it was loads quieter. (Couldn't be arsed to raise the screen, having too much fun)
If you are shorter than 5'11" then I guess it would be ideal. As for eliminating noise completely ..... Go buy a car.
Had bike at optimum speed ;) and still great, although the speed wobble was there for a while, but accelerated through that.
I recommend this screen :)
