VIVOSUN Quiet Register Booster Fan for 𝟒" 𝐱𝟏𝟎" Holes, Cooling Heating Vent with Intelligent Thermostat Control, 10-Speeds Increase Airflow Booster Fan for Bedroom & Attic, Matte White

Bought this to replace one that I had for a couple years. I love this one so much better. The last one just had knob dials and it was hard to get it just right. This vent is next to the wall by a couch so I haven't had anyone step on it yet and can't vouch for that type of durability. It's not as noisy as the last one, it blows out more air too. The air moves the leaves on my mom's plants when I put it on high, it's 12 feet away from the vent. I like that it's not completely quiet because that's know I know it's working and that the furnace just turned on. Sometimes my mom likes to open the door for fresh air and she'll close it when she hears the booster fan turn on, otherwise she wouldn't be able to hear the furnace running since it's on the other side of the house, and pretty much outside. I had to tinker with what low temp to set for it to start running. When set too low it would turn on without the furnace running. I have a swamp cooler, so I don't know how well it works with the AC, just the furnace. Since I bought the house, we've only have one working vent hooked up to the ducts for the whole front 18 feet of my double wide and this vent booster makes up for the other vent in the dining room being closed off for some reason. It's a big job to hook it up since I'd have to tear out the insulation and underbelly material to get the the ducts, this booster saves me from having to deal with that headache of a job. Without a booster, my living room was so cold in the winter. That's the reason I bought the first one from a store, but this one is much stronger and I love that I can play with the settings easier with buttons and digital screen vs little knobs and guessing. It fits perfect, nice and flush with my tile flooring. I have a vent deflector shaped like a "C" with the magnets on it covering the vent so it blows in the direction I need, I just taped it to the floor around the vent so it would stay in place since the booster is plastic not metal. I feel it helps the air flow stronger to warm up more space. This booster and a deflector are a perfect combo if it's not in a place someone will walk, they make ones that push the air straight up too instead of the "C" shape.

Wow what a difference this made in our room. Easy to set up and turn on. Definitely much cooler in our room that gets full sun all day. Solid 10 rating!!Why did you pick this product vs others?:The price and reviews it had

Bought for my son, his room gets hot because of his gaming gear. Works great and definitely brings the temperature down, but setting it up is very confusing and I still don't think I have it right

Not loud at all looks good and helps cool our room. Easy to install good quality and fit

These fans are so loud at max fan speed. I read a max of around 53 decibels. That is the sound of a hairdryer constantly running in the background. I can't slow down the fans, Otherwise the airflow within my workspace would suffer. so I replaced the fans with quieter ones. it turns out that these fans are not special. they are DC controlled 80mm computer fans. So by splicing in noctua fans into the original leads, the fans are now so quiet that you cannot hear them at maximum speed. Obviously the airflow has been cut in half and I cannot displace the same amount of air in an hour as with the old fans. But these are advertised to be QUIET. A hairdryer blowing air 2 feet away is not quiet. Its clearly not and the seller should not advertise that its QUIET.Other than that, it was easy to install. looks okay., and functions as it should. Boosting airflow in rooms that do not have much.Overall, if you are expecting more like a whisper (31 decibels) for these fans, don't bother. the lowest is around the volume of a coversation with no shouting (41 decibles ), to a hair dryer (53 decibels). You need to replace those fans. Thankfully, the process is simple with a soldering iron and a few hours. but for those who want a quiet, all in one solution, go with a different seller.

Not sure if this was intended for floor vents. It did not work very well, actually not at all. The register showed the temperature changing, but however, the temperature did not change in the room. Sending back, not worth it.

Helps keep our upstair rooms cool! Easy to install. Would definitely buy again. They are worth the money.

They are ok but don’t work as well as I hoped.
