Deflecto Mvcx512 Magnetic Vent Covers, 3 Pk (5" X 12")

These are absolutely perfect for blocking a vent off %26 a 3 pack is a bonus. You can paint and trim them to hit. I just wish I would have known about them earlier! Absolutely zero buyers, remorse, and really fast shipping. I got them in three days.

The magnetic seal prevents wasting furnace heat into an unused room.

It does what it says, I like that it can be cut to size, I rounded the corners so it adds style, some other color options would be nice.

They are thick and have a good magnetic hold

The delivery was fast. It was just the right size and worked just like we wanted.

It is so easy to apply and you can made fit exactly

Cover worked perfectly over vent of fireplace. I cut it to size and painted the front. Magnet is strong enough for this purpose

We only use one of the three bedrooms in our house unless we have guests. I bought these to cover the ceiling vents in those two rooms when there is no need to heat or cool them. The vent covers are supposed to adhere to the vents via being magnetized. They fell immediately to the floor - the magnetism being too weak for them to adhere AT ALL to the metal ceiling vents. I am usually happy with my Walmart purchases on line - not this time.

I ordered these to block some overhead registers in our family room. They are not magnetic enough to stick on something on the ceiling. Apparently, they only stick to metal that's on the floor...I could put a newspaper over a floor register and save myself the cost of this product. Luckily, they didn't cost much so I'm not going to bother to complain to the company. I'll probably find a use for them someday...it just won't be for what they were made to do.

If I could give it zero stars I would. Bought these to cover a wall vent and the magnet is so weak it cannot support its own weight. Straight in the trash.
