I bought My1st109's V Stream and it works okay for me. Yes it directs the air toward your head, but compared to no windscreen, it's a definite plus.I had a v-stream touring on my bike when I bought it. I wear a full face helmet and it was okay but too much wind in my face though. I sold it and got a rifle windshield. I like it much better. I am 6'5" tall and like to cruise at 70+.
Just my 3 cents worth.
