In the image above you can see the Corner Shade in his parked position. Notice the gap between the pillar and the sun shade: it is meant to allow seeing semaphores even if the sun shade is down, but the gap allows for the sun to shine through as well. 

Here you can see the corner shade fully deployed. It easily swings out with fingertip pressure.

This is what is visible when the sun shade is at rest. The anchoring for the corner shade and the side extender are barely noticeable.

 

 

To increase stability, when the side extender is not deployed, it slides under the document clip next to the vanity mirror. 

Here you can see the side extender completely deployed. Depending on personal sitting preference or simply body size, a driver may end up sitting quite in the back and, without my product, the car sun shade will not cover the window completely; e.g., I am only 6'1" (185cm) and for me there is a still significant gap left open for the sun to shine through. My extension fixes this completely.
