It blocks the bright light
I gave these 4 out of 5 stars
These universal car shade covers are very helpful. They cover the backseat windows. They block the suns harmful rays but they are great so my son can see without squinting. They can be used with the windows up or down, and when the windows are down they keep bugs from flying into the back window. There are 2 shades in a set. They are stretchy to fit over the car window. It was a little tight on my car, and the foam strip that seals the window got pulled out a little bit but I pushed it back and it seemed to be fine. I would like them to be a little looser but they worked good. They are so much better than the pull down shades, I can't stand those things. In my opinion, these are the best option to protect the backseat from bright sunlight. I received this item at a discounted rate to try in exchange for my honest and unbiased review.
