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)

1.0 out of 5 stars Solution for the Weak Magnetic Vent Covers, February 17, 2010

I read the reviews. Knew I was taking a chance on these things. But they're pretty cheap so took the plunge, knowing I had a back-up plan. Sure enough, these covers won't stay up on a ceiling vent, even with no air flow. So I resorted to back up, which is button magnets on top of the covers. Don't laugh. These are not your mother's refrigerator button magnets. They look unobtrusive but are NOT for sissies. I got some neodymium button magnets (Part No. ZD3) from K&J Magnetics on line ([...]). Pack of 10 for 5 bucks. They are the strongest magnets in the world and it's even hard to pull one from a stack of them. I use six per cover because I like three on the long side but 4 total would likely do. They look fine and make the vent covers do the job which at they fail so miserably on their own.

2.0 out of 5 stars The right size and shape, but magnet far too weak to actually block the air., October 26, 2008

The MVCX512 Magnetic Vent Covers are a bit of a joke. The magnetic force is so weak that not only will they not stay put when the air is blowing, they tend to curl and fall off even when put on any old flat piece of metal. The only reason I'm giving them 2 stars is that they are the right size and shape and sturdy enough to act as a vent cover when taped in place with duct tape.
