Utter waste of money - false advertisingJanuary 18, 2008 This sunshade does NOT work. It does nothing it promises to do. It does not cling to the window of the car. It does not turn dark in the sun - no matter how long it is exposed to direct sun. I found out that it does slowly turn somewhat darker when it is being hit by sun when it is outside of the car when I stuck part of it out the window and rolled the window up in an effort to get it to stay on the window. Completely useless! Oh, and no, my windows are not tinted. And it didn't work for any of the other reviewers on the babiesrus website.
