    Q:Can you paint these covers?
    by|Jul 7, 2023
    1 Answer
    Answer This Question

    A:  The material is vinyl and it will take a special paint to adhere to it. We understand that Rust-Oleum makes a paint that will do this.

      Q:Are these Magnetic on both sides?
      by|Apr 19, 2023
      2 Answers
      Answer This Question

      A:  This is a sheet magnet and it is magnetized on one side only. The white vinyl inhibits the magnet from sticking on that side.

      by|Apr 19, 2023

        A:  No. Also, the strength of the magnet is very weak. I would NOT recommend!

          Q:Is it safe to cover only half the vent ?
          by|Apr 2, 2023
          3 Answers
          Answer This Question

          A:  Yes.  

          by|Jun 13, 2023

            A:  I don't know. It would probably be okay if you were running your air conditioner, but I don't know if the material it is made of would handle concentrated high heat. I use this product to store metal crafting dies on the magnetic surface, so I really have no idea how it would hold up.

            by|Apr 5, 2023

              A:  It is ok to cover half the vent or 3/4 of it.

                I used this cover in ENTRYWAY. I also plan to use one in the Bathroom. I had planned to paint the entryway cover, but it’s “glossy” – and I guess that I’d need to “sand” it a bit, for the paint to grasp. There are no instructions about sanding and/or painting the cover. After Size-Trimming, I made a slit-cut for the Lever. I may sand/paint it another day, along with a better trimming.

                Don't believe those 1 Star reviwers.
                I purchased this product from the store and on The way home I checked reviews and was thinking this was a waste of money. Then I tried it anyway since It was cheap. Guess what! it does exactly what it says. Used it on my ceiling vent. And working perfectly. Note:. 1 cut to size . 2 make holes for screws and the little lever. 3 make sure the vent is in closed position once done. The sheet needs to sit flush..

                  I don't use them as vent covers. I put them on the wall, and I put my metal dies on them so I can easily find them. They are dies for my die cutting machine, and they cling to the black side of the vent covers.

                  I use these vent covers as magnetic sheets to store my (metal) dies for craft projects. I have hundreds of dies for paper crafts - primarily card making and scrapbooking. I cut these to 10 inches put the dies on the dark side and the picture of what it is on the other side, then slip it in secure top sheet protectors to store in a notebook. I have about 25 notebooks. A lot of crafters use the vent covers as magnetic sheets for the same thing. I actually need to go buy some more!

                  ok
                  These magnetic vent covers work well enough on metal vents. I have a few vents that have been painted over and the covers do not stick well with that thin layer of paint.

                    doesnt work with my vents
                    If your vents look like these, they aren’t magnetic and won’t work.

                      I don't understand some of these reviews. Take ANY magnet and put it up your vent. Does it stick? Then this product will work. It's not a strong magnet, so if your vent isn't already restricting the airflow, I can see how that might be a problem. Also, make sure to clean and let dry the surface you're putting the magnet on first. Cut and applied to my ceiling vent and works perfectly at completely restricting the air. Best $5 I've spent in a while.

                        After reading some reviews of this product, I was curious as to my actual need. But, for health reasons, I went up and purchased a pack of three. Returning home, within a matter of a half hour, I had two installed where the need was greatest. the third, I placed in a handy spot in the garage. I must seriously question the truthfulness - OR - the mechanical abilities of the previous reviewers. Both of the units installed are working as advertised and, most importantly, as hoped for. Installation was about as easy as one can get. For a good fit, it is necessary to cut a couple of notches to fit over the screws -1/8 inch each. One other slit for the flow adjuster. THAT was IT! After a few of the previous reviews, I could only respond with "WHAT was the problem?" Oh...and you do have to recognize the magnetic side to place against the metal of the vent.

                          What a total waste of money. These are very thin and their magnetic capability is minimal. I put these on wall vents and the edges lift off and curl away from the vent which completely defeats their purpose. Unfortunately I have not been able to find anything better--the thicker, higher quality ones that I bought several years ago apparently aren't available anymore.
