Good fan.
My old bathroom fan was noisy and low CFM. I bought the fan after watching some reviews. This new one is perfect for small size half bathroom. And I don't need to cut off the ceiling. Its price is competitive. Specially, its mounting brackets are smart design.
My old fan used 3 inch ducting. So I bought the reducer from Home Depot. Please remember longer metal reducer is better, it matches any connector. Don't buy amazon recommend reducer with this fan.

Purchased this for a new build bathroom in our basement. I scourged online retail for a small enough vent since we were mounting into a wall instead of a ceiling. super easy install into the studs and electric connection. I can't believe how silent this vent is and it is VERY powerful. When I first heard it turn on I was suspicious if it was even working because it was so quiet but when I felt the air blow out, I was super impressed. 10/10 recommend!!

My wife and I bought a house and loved almost all of it except for the bathroom exhaust fans! The were so noisy you had to raise your voice to be heard over them. I was actually concerned about hearing damage, so I saw this fan on Amazon, great reviews and they were right! Sometimes I forget the fan is running its so quiet, and while it isn't exactly a shop vacuum in strength it is twice the CFM as the old fan. ( 80 cfm compared to 40)
$60 may be a little more than I was looking to spend but it seems to be well made and definitely quiet! We only have it for couple of months so I can't speak about long-term, but so far, so good! I would recommend it! I put one in each of our bathrooms, just try to into ducting for the existing fan. This fan has a 4"in. outlet & my duct was 3" so I had to buy adapters, and that's another story! Make sure the adapter fits ON 4" to whatever you have on your existing fan. ðŸ‘

I replaced an older fan with a 3 inch duct.
The plastic tabs where the discharge hose connects break easily. I used epoxy to glue them back on. The rest of the installation was straightforward and the fan seems to work fine.

I needed two new fans to replace noisy builders grade that have been annoying us for 19 years. I almost paid twice as much for a name brand fan because it had a slightly lower noise rating but decided to give this one a try based on reviews. Good choice. Most of the replacement work was removal of the old fan including all the insulation that dropped down. This fan fit perfectly into the opening for the old fan so no cutting or enlargement was necessary. Along with these fans I did order a plastic 4" to 3" adapter that costs about $7, knowing that my old fan used a 3" exhaust duct as many homes built when ours was does. This company says attic access is not required for installation. The flanges that are designed to attach the fan to the joist can only be used if you are installing the fan from above. But, there is a groove around the bottom of the fan housing that makes it easy to drill a couple holes and attach the fan from below. If those holes had been pore-drilled, I would have given the installation 5 stars. That give you the additional advantage of placing whatever side of the fan housing that works best with your electrical and exhaust duct against the joist. All in all, a relatively easy job. And, the fan is super quiet. With the bathroom door closed, you cannot hear it at all. For the money, this fan can't be beat.
