So I feel like the average person would see this product and think that it should stick to a metal air vent. Wrong. It has some magnetic force, but not enough to hold its self up. We had to tape the magnetic cover to the air vent in order for it to stick. When I contacted the manufactures about their s***ty product, they said that it was designed to rest on floor air vents. That is stupid and the product is terribly misleading. Don't buy this unless you are buying it for floor airvents.
