This works great on the dash of my Honda Ridgeline, but did not work AT ALL on the dash of my wife's Ford Flex. I cleaned and dried both surfaces and followed the instructions. Also, on sunny/warm summer days (in Virginia), the pad often looses adhesion and I'd have to re-apply. It always holds when re-applied, but it can be irritating. If you are concerned at all about harming your car's dash, this might be worth a try, but next time, I'll opt for the adhesive pad instead.
