Just got....and installed mine a few weeks ago. So, I haven't had a lot of cool weather here in Oklahoma to try it out much. (I have another Cruiser to share the day driving) But, the theory is to cut down on the wind whip/circulation behind the front windshield. So, I've bough some ball caps, and am using heavy hairspary for now!

-install can be done by your 6th grader!
-fit is good!
