Do these vent-visors block any of your view?
I had them on my 4Runner for about a year, and ended up removing them, as they blocked too much of my view, in the area where I needed to watch for pedestrians (in town). I really liked using them, since it rains here so often. I kept the ones that are installed on the rear doors. Mine are the type that slip into the window tracks (not the stick-on).
