When installed, and installed correctly, the shades interfere with the auto up function of front windows. The rear windows catch the edge of shade and will not pass, shade has to be pulled outward for glass to clear. Not pleased at all.
One corner on each visor does not come with the tape pre installed, because this are "in channel" that corner without the tape get on the way of the window every time you are going to put your Windows up, you have to push the visor out.
