Review on Maximum UV Protection Rear Window Sunshade For Car Seats, Passengers, And Pets - Fits Most Vehicles With Suction Cups, By 2Win2Buy by Julio Avikunthak

Basically, the sunshade is too dark - I couldn't see through the window any more! I am including two pictures: one taken when it was rainy, and one sunny. It definitely blocks the sunlight, but it made it so that when I was driving, I could barely make out shapes behind me. I need to return this item for my safety. But if you are looking for a nice dark shade in an area where you don't really need clear visibility, this could be great!The packaging is nice, although the suction cups were squished up. The instructions mentioned putting them in a cup of hot water to make them more malleable, but it didn't seem to help much. However, I tried to just pop the shade on anyway. The cups de-suctioned, but after a few days of sitting in a warm car, the cups went back to a normal shape and on a cooler day I was able to get the cups to stick nicely. No major complaints on the actual functionality of the screen or the suction cups.
