Bests & Worsts Reviews from Amazon

So this product seems to be advertised to keep the heat and sun's harmful rays off of your kids riding in the car, but I don't have kids at home anymore. I ordered these for myself, for those drives where it seems that the sun is directly shining in my eyes from the driver's door window. The 21 x 14 size pretty well covers my entire SUV window. It is easy to see through, so that it does not impact my ability to see others on the road. It is easy to put on the window and pull off the window. It clings and sticks where I put it, but also lifts back up easily. I wish I knew if it was legal to put this on my front windshield for those sunrise and sundown commutes where the sun is blinding. I'll have to find out. I do wish they came in smaller sizes so that the shade could function as a visor extension. Maybe even just small circles to block the sun when it's directly in my eyes.
