Review on 🌞 EcoNour Car Side Window Shade 20x12 (4 Pack) - Baby and Pet Friendly Sun Shade for Complete Infant Protection - Blocks 97% UV Rays & Heat - Rear Window Sun Blocker for Cars by Brandon Miller

This is amazing! I don't really use the more transparent ones because I only use the darkest ones on the back windows for my kid. Something I didn't look at was how they were applied and I just thought they had silicone suction cups, but it's actually a cling-style window blind which I thought was pretty cool. It leaves no marks or anything and the taco folds into an eyeshadow holder. Shades do exactly what the name suggests; They shadow the car. They really shade/darken things and are by far the best shades I've used/seen! It's worth it!
