Aggravating eyesore no more
Perfect solution for an annoying problem. The old air register was an eye sore and I couldn’t stand it any longer so I had to find a solution. I didn’t see these register when I went into the Home Depot but found them when I was perusing their website. The reviews were great except for the odd reviewer that had issues because their vents were likely damaged or the space the wrong size but mine fit perfectly! They just popped in and stayed. Easy to control the heat flow. One problem solved now onto the next! Highly recommend, give them a try. They will not disappoint! Happy house renovator.

Good but not great.
If your duct work isn’t perfect then they don’t sit completely flush with the ceiling. But overall better than using screws.

Excellent product.
The registers were exactly what I was looking for. I installed them on my ceiling vents in the basement. Saved me from making holes in the ceiling.

Magnets are strong. Install in seconds. Vent open/close slide moves freely, no interfere. Worth the money.

    Best for clean duct/drywall openings
    This is a great idea buy works best with perfect ducts. When the ducts don’t line up square to opening the fit is almost flush but not quite enough. 2 went in perfect 2 had slightly gap where it’s just less than flush.

    Ceiling vent
    Worked very well. The magnets are strong and they sit nice and flush with the ceiling tiles.

    Good but could be Better
    Our current home had ceiling vents installed in the basement and the drywallers did not ensure that the venting metal was flush with the ceiling. A vent with magnets attached seemed like an ideal choice to eliminate screws or damage the existing ceiling. After unboxing the new magnetic vents it was obvious they are not made to the same standard as other non magnetic vents. They are about 1" shorter in depth so the magnets barely grip the ductwork, and dont fit tight to the ceiling. I had to pop rivet metal to the vents to have the magnets something to firmly attach. After that they looked and held to the ceiling firmer.

    Not that good
    Magnet not strong enough to hold in ceiling vent..

    Surprisingly well made.
    It fit perfectly. Clicked into place and looks great. The open and close mechanism works smoothly. I'm ordering a few more for my lower level rehab.
