I love this, I keep it in my car at all times. On super hot and sunny days you can instantly feel a different when you put this up. My car can feel unbearable on the super hot days, but if I put this up while I’m out shopping or whatever, I can actually breathe the air when I get back in the car! Now it’s not a miracle worker, it will still be hot, but it definitely helps lessen the blow! It also allows me to be able to touch my steering wheel and seatbelt since they weren’t baking in the sun for hours!
