These are SO much better than the sun shades most people use INSIDE their cars... because they reflect the sun's UV rays OUTSIDE the windshield BEFORE it gets inside the glass. The almost completely prevents the "greenhouse effect" where glass lets the UV rays in which heats up the interior of your car. OUCH. We have had these Intro-Tech windshield sun shades / snow covers for YEARS on our Jeep Grand Cherokee, Chevrolet Corvettes, Toyota Prius, and also our Tesla Model S. AWESOME !!!
