Review on Reflective Foldable Windshield Sunshade Blocks Heat And Protects Car Interior. Effective Sun Shield For Your Vehicle'S Windscreen. Automotive Sun Shade by Paul Randall

I don't know what the "Suction power" rating is supposed to mean which is why I didn't rate it.Overall I would say these are pretty good. They seem kind of thin compared to most that I see.The main issue is that they do not fit properly in my car even though amazon said it would, according to the big green text. The rearview mirror blocks them in a bad way. With some extra effort, they will mostly fit but doesn't fully block the window because of this.The top sides and top middle are left open. Which sort of defeats the purpose, but at least I'm getting 90% sun blocking? The bonus mini sun blockers for the windows were nice though. Comes with a carry bag as well. Though I don't use it. Simply fold and toss behind the seat.Not worth the effort to return, but I will definitely be getting new ones for next summer. Gave it a 4 because they seem a bit thin to me and they don't fit my car properly. Otherwise would be a 5star.Edit: Removed a star because they don't really help with the heat. Been using them a while now in the 30c weather. Blocks the sun (mostly) since they don't fit properly. They are too thin to help with heat and 0 insulation. Not really worth the money.
