Customers are mixed about the noise of the fan. Some mention that the actual unit is pretty quiet, while others say that it runs louder at full speed. The noise does not carry to the second floor, but is quite audible throughout the first floor.

Customers are mixed about the value of the fan. Some mention it's not bad price wise, has a good cfm to cost ratio, and is a very inexpensive fix if you have an upstairs that is too hot or too cold. However, others say that it'll make an awful, loud, high pitched whine. It's a miserable product to live with and does feel a little cheap.

Update: Has been going strong 24/7 for three years
I was upset about the noise level of the fan. That still holds, but am quite impressed that it has been running 24x7 for about three years now.Original Review: Poor motor isolationOne of the 2nd floor bedrooms has poor air flow and is too cold in winter or too hot in summer. I installed this booster fan in the 6in duct in the basement feeding the room just before it transitions to an in-wall duct. My decision to select this product was:+ the fan housing enlarges to about 10" diameter. This prevents the motor taking precious area and reducing the available cross-section area for air flow which effectively chokes the fan.+ Includes fan speed control to tune the air flow+ Large number of positive reviews on AmazonThe installation was fairly easy once you cut the galvanized duct to the proper length. Since my basement has a finished ceiling I had to install inside a closet where the duct was exposed. I removed a section of the duct that is almost the length of the entire booster fan assembly and secured with 6" hose clamps and sealed with aluminum tape.Once running, it gives a good boost with a reasonable amount of wind noise at the floor register. With the fan control set at about 1/3 the speed range it gives a good flow (about a 12ft rise to the 2nd floor bedroom register).The downside is that there is a humming noise transmitted throughout the entire galvanized duct that is quite noticeable. The noise does not carry to the second floor, but is quite audible throughout the first floor and basement where all the registers are connected via galvanized ducts. You can hear the hum under the1st floor where the ducts run under the floors. I measured the sound levels with my phone:1ft from the booster in the basement: 23.9db (fan off) / 43.2db (fan on)In the finished area of the basement (home theater): 29.1db (fan off) / 33.5db (fan on)1st floor dining room (right above the duct with the booster installed): 20.9db (fan off) / 48.0db (fan on)

Reviewed in the United States on June 17, 2017
I got 2 of these. Im so impressed w how quiet they are while still blowing plenty of air, i got 2 more. I own a couple more expensive fans that are being replaced with these for noise reduction.

Edit: 4 months into running these fans 24/7 w no issues. I want to add that i run them at about 3/4 speed and unobstructed. If you turn the speed down the fan motor will whine, all the way up and the wind noise goes up. The motors are fast but weak, so they blow plenty of air when unobstructed, but bog down easily. So, good for venting a small box, not as good for a carbon filter. Although they will work with a small filter.

Edit march 2018. Almost a year now. 2 of these fans have been on 24/7 and 2 of them turn of/on for venting. No issues with any of them. Theyre all still extreemly quiet and ive seen no loss in power.
