This window sun shade is a very well made and sturdy product. It's very thick and durable. When I first opened the package, I couldn't believe how thick it was. I can feel how much cooler my vehicle is at the end of my work day, after my car has been sitting in the sun all day. There's very little shade at my work place. The thin, store bought shades don't deflect much heat, but this shade sure does! Great product! Pricey, but well worth the money spent!
