For those of you with window visors, I was wondering if they cut down on the wind noise when the windows are open. Also if you have pics and the brand name of the ones you have that would be great. I am having trouble finding pics of what they look like on a Mazda 6. Most pics are just generic pics of the visors not installed. I'm looking to get some for the wife's Speed 6 and want some more info before I decide.
