It does precisely as advertised - it fits the windshield properly, and it blocks out the sun to keep the cabin cooler. The first part is no small feat as it%X92s very awkward to fit such a small windshield combined with such a large sensor and electronic area around the rear view mirror %X96 but it does the job and it does it well.
Great sun shade
I have a Mini Cooper Clubman and this sun shade is just what I need on hot, sunny days. Due to the curvature of the window, it is a little difficult to set up just right, but once it's in there it's a perfect fit. I have one for my other vehicles and it's much easier to place in the window due to the larger vehicle size. I would definitely recommend this sun shade. It's not one of those flimsy shades either. This will last forever.
