My daughter wanted to rearrange her room and every idea she had involved covering her vent. We looked at multiple vents and this by far was the best.This vent is made of very thick and sturdy plastic. It has a hard consistency to stand up to use and not fall apart with wear. Many other vents were either very flimsy or would quickly fall apart with any use.My daughter took it upon herself to rearrange her room and set the vent up. She has not experience using them before and was able to set up the vent without any assistance. The vent is easy to extend to the length that you need and can be adjust to direct air flow as you need.Pros: Very sturdy construction Easy to set up/install Adjustable length for desire air flowCons: Nothing to report

In my overly-occupied living room, this is just what I needed. My vents are all close to the wall and so is my furniture. This redirects the air flow to where it is needed—from under the furniture, not in it. The temperature is much better now.

This is a really nice tool. I have always had to plan where furniture was in a room taking into consideration where the vent is, but this opens a lot of options. Most furniture has a little space underneath and this redirector makes sure I am able to push the air towards the center of the room rather than it being trapped in the dresser or blowing up the wall into the window. The two extension parts work perfectly, it did take a second to realize the particular order they need to overlap to make it work, but once you do it then it's solid.Check the space under your furniture, keeping in mind a lot of furniture has a taller gap in the middle than around the edge.

I have bought the cheaper vent extenders previously and they don't hold up.This one will I'm sure, its thick acrylic and has 2 extenders, so it will reach way under the furniture as needed. I feel like this will keep the air flowing good and straight out from under instead of going up into the couch and possibly ruining the furniture.Good quality, thick acrylic, great deal.

I'm lucky enough to have the metal heating registers by the wall, so I was able to use the magnetic cover without using the stickers they supply. It can be extended to 3 times the basic length, but I only needed the first piece, which goes over the vent and redirects the heat/cold out of the end.This is perfect for me, since I have the TV stand over this one vent, and all the heat just hits the bottom of it rather than going into the room. This redirects that air under and out of the TV stand, which now goes into the room - way better!It was really easy to install too, since I basically just had to move my TV stand and place it on the vent, and move the stand back. Perfect!

Ever rearranged furniture in a room and had the perfect setup in your mind only to be foiled by a floor vent that would be directly under a couch, chair, or other piece of furniture? Of course you have and this product helps that room design become a reality. Well made and helps the heat/cool get to where it needs...the room and not into the bottom of a piece of furniture. Naturally, there will be some pieces that this may not fit under, but for most it will work well.

I have a vent that sits under the stairs. It blows up and out of the room. This vent extender works great for redirecting the air. It came in a box with three parts, little stickers for non metal vents and instructions. It was pretty self explanatory but it's a good thing to get instructions. The metal magnets slapped onto my vent perfectly and the extension slid right out. It's pretty much invisible. it's very well made. I'm impressed

GREAT concept for vents that would otherwise be blocked by furniture, etc. Super easy to place over the vent and even though mine is wood I didn't bother securing it down since it's under a curio cabinet in the dining room and people rarely walk around it. One thing I think (maybe?) could improve this product is if the extenders were height / opening adjustable- Meaning if you could make the opening taller if you have furniture that didn't sit so low to the ground. It's pretty pricey for just one unit and not super sturdy when fully-extended but it solves an otherwise problem that I'm sure many of us have.

The box for this gives you a great first impression, and it doesn't let down from there. The magnets are notched for proper installation, which is nice because mine came loose during transit. The plastic is nice and thick, and not like takeaway food lids. The width was absolutely perfect for my needs, and the length I needed was perfect as well. The magnets are strong enough that I'm sure this would work in a vertical application as well. Magnetic stickers come with in case your vent is plastic, but I'd highly recommend a metal vent.I'm super happy the alternate brand I ordered was undeliverable, because I wouldn't be as happy. If you need a vent extension, this is the one to get.

This device effortlessly redirects airflow, ensuring consistent temperature distribution throughout the room. Installation was a snap, requiring no tools, and its adjustable design allowed me to customize the length of the extender. The magnets hold on tight to my metal air vents. Made from a durable plastic, it seamlessly blends with home decor with its clear color and low profile. Since incorporating it, I've experienced a noticeable improvement in temperature balance, eliminating uncomfortable hotspots and drafts. In summary, the Air Vent Extender is a must-have for anyone seeking to optimize home comfort and efficiency.

I really tried to get a picture of this under my furniture, but no picture did it justice. Hopefully my words can do it justice.I wish I had discovered this thing 5 years ago when I moved into my house and got my sectional delivered. My vents are all on the floor and my section is GIANT so at least 2 of my vents are covered by it. This has made it difficult to regulate the temperature in my living room, and because my thermostat is in my living room, it has been difficult to regulate the temperature throughout the whole house. Now that I have this vent extender over the main vent, I am hoping it will improve. The vent extender was not the easiest to install but that is only because my couch is low to the ground and deep/wide so it was hard to maneuver it underneath the couch, but I was able to get it done on my own. I will say that the magnets are strong so make sure you have a stick or something you can use to lift the plastic over the vent, otherwise it might get stuck where the magnets first connect to it. My issue was getting it over the adjuster/latch on my vent. I was able to inch it onto the vent but because it was magnetize, it was difficult to get it over without some help from a sturdy broom handle. Once I got over the latch, it magnetized to where I wanted it on the back. I will definitely be back to order another one once I find my other hidden vent.

Our sofa is directly above two of the three floor registers in our family room, so we were excited to give this product a try to help with the air flow. These worked exactly as described - given that our floor register is of the 2" x 12" type, the length was plenty long enough to fit over the top of one of our vents, with the magnets helping to keep this extender in place. We dragged the extender out as far as the tip of the sofa and checked that the airflow was redirected as we intended - into the room and not stuck underneath the sofa. It remains to be seen in terms of how helpful the changed airflow ends up being in terms of the room temperature, but we are happy with how the product has functioned for us so far.The reason I knocked a star off is because of the price - this is much pricier (about 2x) compared to other vent extenders that I have tried which have similar functionality. While I have no issues with how this product functions, I am not sure if it really merits the higher price.

In our living room, the only vent is located under the only location where a couch could reasonably be placed, so we've always had most of our heat or AC get trapped under the couch. Until now, this is the exact fix for that problem.Not only does it reroute the air from the vent almost 3 feet away from the floor register, but it isn't one of those diverters that is so massive in height that you can't install it underneath furniture. It provides a tunnel about 2 inches high for the air to be diverted anywhere from about 12" to almost 3 feet from the vent.The device is 3 pieces of plastic that slide into each other. You either use the built-in magnets to secure it to your metal floor register, or you use the included 3M adhesive patches to stick it to the register. We have wood floors and wooden registers, so the adhesive patches were what we used. They went on quickly and did the job. We have ours extended to about the depth of our couch and now the air from that floor register comes to the front of the couch and into the room quite noticably. So much so that we can now feel actual airflow coming from under the couch when the heat or AC is on. Before, that heat would be trapped.The only improvement I might offer is to create the nesting effect with the 3 pieces so that A (where the register piece is) is the smallest, B (the middle piece should be next largest), and C, the front (where the air escapes) should be the largest. This would allow the airflow in the device to leak less. As it is designed now, C is smaller than B, so you have a built-in gap (miniscule, but still a gap) where you're forcing air into, and clearly will leak. We minimized this with simply taping the pieces at the gaps once we determined the proper length. However, a small design change like mentioned above could have mitigated this leak pretty easily.Overall, we're very happy with the product. It does exactly what it promises, and it will be a part of our living room for years.

My son's crib is over the air vent in our room and we needed something to redirect it so it wouldn't get so hot/cold directly on him. This is awesome. It redirects the heat and air to the center of the room. It's a thick but slightly flexible plastic. It's super low profile. If you have a couple inches of clearance under furniture it'll fit. It connects with magnets or if your vent is plastic or wood, with 3m tape. It's great quality I like how long it goes. The ones they sell in the hardware store are way taller and don't extend past the vent like this one does.

This is perfect when you have furniture over you floor vent and the air flow seems blocked You can divert the flow to the edge of the furniture so it blows into the room and not under the couch. The magnets are strong. The one issue is that you have to tape the 3 units together and the tape does not seem like it is going to last very long. I used clear packing tape to hold them together.

I have a vent/register under a couch. It makes the couch nice and warm, but not so much the room.Apologies for a photo that isn't up to my normal standards, but as soon as this shows up, I installed it and it has been redirecting the air from under my couch into the room.It has 3 parts that can be used to make a shorter or longer air path depending on your use. I needed all 3. The magnets are strong. Getting the 3 parts to nest together is a tad finicky, but manageable.Mine has already survived an accidental kick, but beware if you step on this, it's likely going to crack, so be careful how far you extend it into any walking space.

Magnetic air vent extender is the greatest ! I wish I had these 40+ years ago. Easy to install. Simple easy to read instructions. Nice sturdy thick plastic. A big difference in air flow compared to cheaper extenders. Note: In the section that has the magnets, one of my magnets fell out and had dropped onto another magnet. Okay so am I the only one that has cut boxes up to make vent extenders ? I will spare you the other photos but before this was installed I had one of those cheaper plastic ( think soda bottle type plastic ) duck taped to my floor because the air would blow it away. I have an old plastic one under our bed now that has something weighted on it to keep it from blowing away. All this wasted heat and cooling because of the lesser quality of extenders. What a difference in the air flow coming out right where we need it. I am Thrilled to have found this !! We will be getting a couple more of these nice sturdy nicely weighted extenders!

I am really glad I ordered this for my bedroom because my floor vent is behind my bed and usually blows straight up. A lot of nights I wake up from being hot and sweaty because of the floor vent but this extended works perfectly at directing the heat across my floor. My bedroom temperature has been much more consistent with keeping it comfortable because the air flow is much better now.

I have struggled to heat my living room for years due to the placement of the heater vent being under the only place to put our couch. This vent cover holds on to my heater vent SUPER TIGHT!! I was surprised at the strength of the magnets. I didn't even need to clip the ends over the back of the vent (clips are part of the plastic design) because it held so tightly with just the magnets. It's easy to put the other 2 slides on and move them to the desired length. I used a good 30", securing them in place with the included stickers) and now I have a blast of heat coming out from under my couch. I can feel the heat across the room. I only wish I would have found this product sooner! 5 solid stars and worth every penny!

Everything about this kit is 1st class and that would include the price. I had a specific use-case where our chest of drawers covered one of the vents in our bedroom. This kit worked perfectly and allowed me to adjust how visible I wanted the vent that was redirecting the air. As seen in the pictures, the kit comes in a very nice box with a nice personalized letter from the owner. The functionality is great as the pieces lock together to make a sliding "tunnel" that can redirect air for just about any depth situation you may have. The only deduction I made was that you can purchase these kits at big box stores at a significantly discounted price and you are paying a premium for this particular kit. Overall I rated it as 4/5 stars for a very high quality item.
