Comments on using VentShade products?

I was thinking about purchasing a set of the VentShade Ventvisors for all 4 windows on my 03 Runner. Toyota does not make their own so I have to go aftermarket. Has anyone have any comments on those that have used them or bad outcome with them? Info is much appreciated.

I have used Ventvisors on 3 vehicles with no problems. Just be sure to clean the mounting area per the instructions.
