Saw these Magnetic Floor Vent Covers and thought I'd try. WOW what a difference it has made on keeping the room warmer.! Super cheap 4pk and fits a standard size vent and smaller. You can easily cut it to fit if needed. These Magnetic Floor Vent Cover stay in place even in high traffic areas of the home.

Works great more than I thought and it keeps the eye out no sand no seasoning. It is a very good design. You might consider using it if you wanna keep your stuff cool works great more than I thought and it keeps the eye out no sand no seasoning. It is a very good design.

I'm giving these a five star because it was just something that was reasonably priced that I could do a little upgrade in my home or just a little to nothing. The covers look nice. I do not have central heat and air this house had it at one time so I just wanted to cover the vents and look nice.

Only ordered one to try and very pleased with how they fit over unused air vents. These will help cut heating costs this winter. Definitely ordering more.

Very nice quality, perfect size for my vents, they fit them perfectly. I'd would buy them again if I needed to.

did not fit the vents had to use two of them and still had air coming out from under the cover will have to find something better to cover vents in the summer

Good, but a tad wider and longer would be better. Magnet needs to be a tad more powerful when using on overhead vents...not as solid a grip as I would have preferred. Fortunately trimming easy to fill gap and connecting tape good.

no matter how hard you try it doesn't lay flat. The magnetic does grab great but it just isn't laying flat.

Liked them until later that day the magnets started peeling off the back once the heat eas on a couple of times. I can correct it but would expect it not to do this. also, they look good but do inhibit the heat coming through the vents.

I want to return this item. My vent registers are aluminum and these vent covers need metal for magnets--as these vents must do.
