Product Review: Magnetic Vent Cover 5.5 x 12 Inch - 3 Pack

 

These magnetic vent covers fit well over floor vent covers and do a good job of eliminating airflow from the vents. However, they will not remain attached to some ceiling vents and can easily fall off those, especially the kind that has a vent control that is like a handle that sticks out from the metal. I am not sure if they would stick better if you have a ceiling vent that you can lay them all the way across, and have them sit flat. But on the kind where it would have to be placed off-set or off-center because the vent control gets in the way, they will easily fall off.
