I definitely noticed a difference with the absence of wind hitting me in the chest and even on the lower part of my face. But when I went up over 80 MPH my glasses would start to flutter on my face. I didn't like my glasses flutering and I could feel the wind hitting just under my glasses. As I posted earlier if I was an inch or two shorter or had a low profile seat I think it would have worked great for me. I also liked the looks of it too.
