I got the heat shield product for the windshield and 4 passenger doors on my Model S. Windshield one is great but you can't really get out of the car if you suction cup all the passenger door ones on the Windows. When you open a door the window for that door opens slightly and thus jams the heat shield into the bottom part of the window sill. In the back, the suction cup on the wing window prevents the door from properly opening without straining the heat shield. Still love the product though. Car was almost 10 degrees warmer with shields in place!
