Rated 5.0 out of 5.0 by Nevv This product is fine.
I cut these covers to fit and they stuck to my ceiling vents just fine. I should mention that I did make little cutouts for the slide (in the closed position) and the mounting screw heads to assure the covers fit flush with the surface of the vent. Turned on the air and they didn't budge. t think many of the complaints in other reviews may have to do with the fact that these covers won't stick to aluminum/plastic vents (nor to stainless refrigerator doors, which aren't magnetic either). It's also possible that some vents just don't have enough solid metal around the louvers to allow the magnet to stick well. I do think making cutouts for the slide and screw heads helped give me a good result. I'm glad I ignored all the bad reviews and decided to give these a try.

Rated 4.0 out of 5.0 by Bart works great on floor vents
I read the reviews of this product and bought it anyway.
First, make sure your vents are of an iron product, (ie: steel), not aluminium or brass. Second, yes is does stick to itself. If anyone finds it does not, take it back. It may not have been magnatized fully.
I am using it on some floor vents. Make sure the register is clean. I found that if you cut it to the exact outside edge of the register, then hold it firmly in place, especially at the thumb wheel, it seals great. But, it only comes in white.
I have some ceiling vents downstairs. I will try it there to see if it works.

Magnets is very weak! Doesn't stick to a vertical surface and I didn't even try covering up the registers in the ceiling because I knew they wouldn't stay up there without me holding them.
I returned these 30min after I bought them.
Best advice I can offer...unscrew your HVAC register from the wall and pull it out. Grab a black trash bag, fold it up so it's about 1" wider all the way around the backside of the register and block the vent from the backside. As you push the register back into your vent, the trash bag gets wedged in and creates a pretty good seal. Don't forget to remove these as the seasons change.

Rated 4.0 out of 5.0 by Mike IMPORTANT REVIEW!!!
Past bad reviews take notice. I read all the bad reviews and still bought these vent blockers. The price was right, a 110 degree day in VA, and two vents that wont close so I stayed positive.
I cut one to the size of my vent on my ceiling and it fell to the ground... Used common sense and cleaned the vent to prevent dust and held it back up to the vent and pressed firmly focusing everywhere except where the screws were and lever to open and close. After a few miniutes it is like it formed itself or joined to the metal and 24 hours later it is still up there.
Note: the AC was running at the time and I used a bit of scotch tape. 24 hours later scotch tape not holding but magnet still there. Not sure if the tape helped at all. I think I used it just in case. AC and scotch tape dont mix with cold temps.
I would have paid a bit more if these were a bit thicker/stronger magnet and whiter color to match better with the walls.
End note, patience and common sense.

Rated 5.0 out of 5.0 by Brittany Worked Great !
This magnetic vent cover did the job.
We closed the air vent with the lever, and the magnetic cover blocked the rest of the air that was coming thru.
One thing to keep in mind. The vent has to be metal, and there cannot be too many layers of paint on the vent. So you might have to remove some paint from the vent, if there are too many layers.
Too many layers of paint will prevent the magnet from touching the metal. Worked great !

These magnets can barely even stick to a fridge door. They can't even stick to one another, how are they going to stick to a ceiling vent when the air is on full blast?

Rated 1.0 out of 5.0 by akuki Doesn't stick when regular magnets do.
I would recommend finding your vent in the store to test this product before purchasing. It doesn't hold at all for my vent, while regular magnets do.

Rated 4.0 out of 5.0 by Paul Make sure your vents are not aluminum before buying.
I bought these covers and was initially disappointed that they didn't stick to the AC vent. A bit of investigation revealed that the vent assembly was made of aluminum. No magnet could possibly stick to it. I tried it on another type of AC vent and it worked as advertised.
