I have the National Cycle version and I like it a lot. I am 5'11 and it takes the wind blast off my chest. I wear an open face helmet and it works well for me. I dont do any long distance touring but do spend a fair amount of time on the freeway at freeway speeds. It does require some trial and error adjusting until you get the angle right for maximum effectiveness. Its not a full geezer windshield but it works surprisingly well for how small it is.
