I figured it was only $20 & they offered a full refund if I wasn't 100% satisfied. So I bought it & tried it out today. And I was extremely impressed! It did an incredible job. The only place I noticed water beading was on the molding on my front windshield, but not on any of the other windows. There were a very few places where there'd be a drop of water or two & I just swiped them with the chamois, but all in all it did a great job. Even on my wheels & tires. I have chrome wheels, so I expected them to be all spotted, but not at all! It didn't strip my wax & my paint even feels softer than before. I think it's even cleaner! I noticed my sponge was really dirty & when I looked at the FAQ here's what it said: "...Mr. Clean AutoDry Carwash is so great at cutting dirt..." I need to get a new sponge now, but I'd rather have the dirt on my sponge than on my car. And the soap even smelled really good! I would definitely recommend this to anyone who, like me, doesn't mind washing their car but hates drying it! It even saves time because while it's drying you can be cleaning the interior or doing anything else! SOOOO WORTH THE $$$! Cliff Notes: Mr. Clean AutoDry kicks ass! No spots- even on wheels & windows Car cleaner than usual, paint softer Highly Recommended!!
