Needed covers for cold air coming in vets. The best thing about these for me, is that the materials did not smell toxic. I am sensitive to chemicals, and magnetic sheeting usually smells, but not these.

Great quality
I got this for covering vents. I was surprised at how well made it was. Nice and thick and the magnet works great. I'm very happy with this purchase.

Magnet Vent Cover
Did not stick properly or work on ceiling metal vents. Will work good with floor vents.

Save your money, dont buy
This is the worst purchase. They do not even stay on, we tried taping them but as soon as the heat kicks on it pushes the tape off and as you can see in the picture is just a flap. This is the weakest magnet ever and such a disappointment.

Not for ceiling vents...
Total waste of money. I can not speak on if these work for floor or wall vents but, for ceiling vents, they do not work. They are too heavy and the magnet is too weak to hold them in place. Extremely disappointed.
