I have them (adjustable) they do pretty good, in the winter i also put the chrome side (fork) deflectors and cust down on the cold...I am thinking of changing mine to the freedom wings...they seem to let more air in.

 

havn't got them yet, wont be delivered till monday

 

If you're looking to clean-up dirty air (buffeting) from the front - fairing wings help, but adding HD's fork baffle (one under tree) along w/wings definitely works quite well. Only thing different on my bike is added vented lowers & all three make riding a batwing much more tolerable. Cheers!

 

I have all three front deflectors, took all three to make a noted difference, have since added vented lowers and not sure if I still need the side deflectors.
