I don't have a strong opinion one way or the other but my guess is that those who have had a bad experience with the duster didn't follow instructions. When it is new, it should be set aside to DRY for a couple of days or so. Otherwise, it could leave "wax" marks on the car. Secondly, one should use a LIGHT touch when dusting....with just the tips touching the surface. Thirdly, shake it frequently to rid it of the dust that was picked up. Last, only use it for DUST or POLLEN....NOT for DIRT.
As I said before, I only use it when my cars are freshly waxed and slick. I have had no ill effects but I am neither recommending it nor am I saying it is the devil in disguise.
