(More customer reviews)This product does not have strong enough magnetic force to hold the weight of the vent cover against gravity.I have sheet steel A/C vents.The covers barely hold on to the wall vents and don't hold at all to the ceiling vents.When the A/C fan came on, the wall cover fell to the floor.I compared the magnetic strength of the vent covers with photo magnets from Shutterfly by applying the vent cover to the refrigerator.They both held with the same apparent strength.I tried to attach the photo magnets to the wall vent.It held, but not as strongly as to the refrigerator.The problem seems to be the amount of ferrous material in the vent cover and the shape of the cover - mine were stamped by machine and the built-in air deflectors in the vent are raised slightly from the edges of the vent where they attach to the wall/ceiling.There isn't enough flat surface for the magnetic covers to grip.MVCX512 Magnetic Vent Covers (5" X 12", 3-pk)
