I wanted to like this thing, it does clean dust off your dash but it leaves behind little red particles nearly everywhere in the 3 vehicles I've used it on.  It seems to be worse on textured surfaces but it will also leave red particles behind on your touch screen, gauge panel and just about anywhere else you use it.  Never had this problem with its full size vehicle exterior counterpart. Maybe that gets better with time but for something that is supposed to clean it sure is annoying to have to pick tiny red threads and red dust off your cars interior.
