## Questions & Answers

**Q: Would this work on a ceiling vent?**
A: to be honest, I tried Bomic Magnetic Vent Cover 5" x 12" after I realized how bad this product was. The Bomic Magnetic Vent Cover fit perfectly on my vent. Also it is super strong and sturdy . The magnetic itself is quite powerful. I high recommend theirs if you are not satisfied with these vents.  https://www.amazon.com/Magnetic-Vent-Cover-Sheet-Pack/dp/B075H3S34C/ref=sr_1_11?ie=UTF8&qid=1505497181&sr=8-11&keywords=magnetic+vent+covers+5x12

**Q: How effective are these at blocking heat?**
A: This will block the air flow from a forced air heat vent. They come in different sizes for different size vents. Order one that fits the vent(s) you have. You can purchase a smaller one to block only a partial vent. However, they are not very strong magnetically, so if there is any air pressure at all, it could be ineffective. The more vents you have blocked, the more pressure you have in the system. If you are blocking a lot of vents, it might be better to turn down/off the heater altogether and use an area heater for the area you need the heat. Another solution is to buy an adjustable heat vent that has a lever that you manually adjust the air flow for one vent. Warning of caution though, don't block more than 50% of you vents, this will cause too much pressure and possibly cause a problem blower motor or blow a hole in the the ducting, both of which can cost a lot of money to fix. Even worse, over working the blower motor and backing up the heat in the heater could cause a fire.

**Q: Will this work on a wood floor and vent?**
A: I used it for a floor vent and the air conditioner blew it right off.  I didn't try it with the heat. They are not strong enough for what they are suppose to do.

**Q: Are the smaller vents adjustable by hand?**
A: This isn't a vent, it's a cover that blocks off the vent.  The idea is, why heat rooms you aren't using?  This allows you to not heat those rooms.

### ⭐⭐⭐⭐⭐ Delivered on time

Fantastic!!! Delivered as advertised.

### ⭐ magnet is strong enough to hold it on a floor ...
*by B***! on October 13, 2014*

We have an older 3 level house with one AC zone to control temperature. It takes careful tuning of all the vents and returns to get each room to an even temperature. We were looking for something that could help us adjust flow and return at a minimal cost. We came across this product and decided to give it a try. So we thought these would help as the vents being in a closed position is not enough of a seal. Conceptually the magnetic vent cover would be a great solution. However, the magnet used in this product is strong enough to only hold it on a floor vent. Keep in mind your vent grill does need to be metal as many decorative ones can be made of plastic. We tried putting it on wall vents and on ceiling vents. Neither one worked, the cover would just fall off. It did not work on the return vents either – where the flow should be into the vent as opposed to out of the vent where it would push the cover off. Overall - I do not recommend this product, you are better off just getting a piece of plastic and wrapping around the vent or place something behind to vent to limit flow. I was not given a discounted price or offer for a review of the product. We know how hard it is to assess a product from a picture on a webpage. I hope that the review can help you make an informed purchase.

### ⭐⭐⭐⭐⭐ Pleasantly surprised after having very low expectations.
*by A***C on July 18, 2016*

I bought this product with very low expectations. I read all the reviews that said that the magnet is very weak, and the packaging itself says that it's not meant for ceiling vents. But I had some Amazon credit and decided to give it a shot anyway.After receiving the product, I'm pleasantly surprised. I gave it a try on two ceiling vents and it sticks! Sure, the magnet is very weak, but I guess that if there's enough surface area on the vent, the magnet is just strong enough to hold itself to the vent. It might be worth noting that the vent covers I bought are larger than the vents that I have. My vents are 7"x13", and the covers I bought are 8"x15". I figured that I could cut them down to size and place them inside the vents themselves if they didn't stick.Besides, if you have a bar magnet or a set of neodymium magnets, you can use it to reinforce the vent cover. In my picture, I stuck some magnetic buckyballs to the vent cover for demonstration, but they're not actually required for the cover to stay on the vent itself. If you already have a set of aesthetically pleasing bar magnets or small button magnets, I think these are a very viable solution to covering up vents. I did NOT receive this product at any discount. I paid full price.
