I just tried it for the first time today. If you're looking to put one on to deflect the wind when you have the sunroof open, it does deflecting most of the wind. There is still some that goes in but not enough to create a lot of wind noise or to bother you. I might actually remove it, but I'll give it a few more days before doing so. I thought I didn't like the wind coming in from the sun roof, but now I realize that I do like it. Also, the one I have seems a bit big. I'm not sure, maybe I just haven't gotten used to it. I'll evaluate it a little more to let you know.
BTW, is there a AMA (Automotive Modders Anonymous) I can go to?
