Nice product, easy installation and fast shipping

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.

Magnetic Floor Vent Covers

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.
