Worked surprisingly well for flimsy looking silver cloth material. Really kept the black leather of my Acura MDX cool in the blazing summer sun for a while. After a couple months something happened to the metal wire that frames one of the sunshade cause it stopped folding right. One sunshade would still fold into itself so I could tuck it away, but the other sunshade became stiff or something and stopped folding well. Then that same metal wire frame started poking out of the border of the cloth material of the sunshade and started stabbing me and my husband whenever we'd go to fold it. About a month after that, the frame didn't just poke out a little, it came ALL the way out and so we had to throw it away. Sadly a couple days ago I discovered the one sad remaining sunshade has a frame poking through a little bit so I'm guessing I'm gonna get another week or two of use before that one goes kaput too. Got a total of 3 months use out of these sunshades. What a waste of money.
