Review on 🌞 Premium Car Windshield Sun Shade - 210T Polyester Heat Block UV Protection Sunshades for Optimal Sunlight Blocker, Reflective Sun Visor Car Window Shade - Convenient Storage - Essential Car Accessories (Medium) by Muharik Khalifa

I don't understand the complaints. If you need an "eBook" to use the sun visor, you probably don't have a driver's license. I bought a medium for my 2003 Chevy Silverado and it fits perfectly and works well. As for the rear-view mirror (I just don't understand some people) - the curtain is put on the mirror, on your side of the mirror. It can't go under the mirror because if you look you can see the mirror is attached to the windshield. I swear I don't know how some people get out of the house. It folds up easily. The fabric is thin. Does it have to be thick to work well? No, the concept is a reflection, not an isolation. It only reflects the sun's rays outwards, so the thick material doesn't add any value. Thicker material doesn't last longer either. The reflective surface is very thin. A thicker backing will not make the reflective surface thicker. If it breaks after a few years, it would be more correct to throw it away and buy a new one. They wear out and the thickness of the material doesn't affect it.
