I'm looking for an auto windshield shades for the front window of my car - and I don't want one of those awful cardboard ones!!!!

A coworker recommended the Eclipse Sunshade (he said he got his at www.eclipsesunshades.net - has anyone ordered from them?).

It looks like it attaches to the windshield. Does anyone know anything about it? Is it any good? How easy is it to use? Is it durable? I'm nervous about ordering one online until I know a little more about it. Thanks!
