I have been in cars that do not have any built in sun shade or tinted glass. When the sun glares in at me, I can't see where we are going or even see out. Now they have designed sun shades that are very easy to install. We installed this unit on my husband's rear windows of his car. The roll up shade pulls down very easily and there is a little button on the main pole that rolls the shade back inside. The accompanying suction cups were a little difficult to get in the slots but we finally were able to get them in and stick to the glass. With the roller shade pulled out, we were able to see the difference they would make even on his tinted windows. Visibility was still clear, without any glare. These would be great for protecting babies and young children from the glare and contribute to their comfort on long rides. Easy to install and store.
I received this product at a discount in exchange for my honest and unbiased review.
