We have a son who does not like to have the sun in his face. I have tried many different sun blocking products; the roll up shades, the suction cup shades, and now the cling shades. Hand down, the Eddie Bauer Cling SunShades were the best, and the cheapest. The Eddie Bauer Cling SunShade attach easily to your window, and can be removed and reattached very easily. They were inexpensive and have been in our car for well over a year now with no problems. I love that we can roll the window down when it is nice outside and not have to take the Eddie Bauer Cling SunShade off the window. The only con that I have for the Eddie Bauer Cling SunShade would be that they do not come in different sizes. The widows in my car are larger than others, and the shade does not cover the whole window. This is not a big enough of a con to not purchase these again for a friend as a gift. The Eddie Bauer Cling SunShade are a great gift for a new parent!
