I got the 16 inch shield with vent for my Fatboy. It works great and I am very pleased with it. There is still a little buffeting but it is much better and the vent helps to direct it away from my head.
Perfect vent when you want some air but also want to eliminate that negative air pocket behind the shield. Little loose up and down but does not make any noise at highway speeds.
I'm currently deployed and the vent was delivered to my wife. My initial impression before install is that the vent is either used or poorly made. There are several imperfections throughout. This seems like it was either returned by another customer or missed the QA checks. I will update my review when I see it in person and install.
Very cool design and fast shipping.
I had some small issue with my shield and the y replaced it promptly.
Bought the 20 inch with vent absolutely love it!
