Absolutely terrible
I'm pretty sure this piece of junk is just a noise maker, not a fan at all. It's annoyingly loud at 30 feet away, around corners and through walls. By the "toilet paper test" it appears to not be moving air at all. It also seems to be sucking air in on one side and blowing it out on the other, which indicates it's not actually exhausting much air out at all.The install is very annoying; the actual fan unit is in 4-5 separate pieces which are not well held together; anybody who has the first idea about quiet fan construction would know right off the bat that this not going to work. If you have to do an unusual install at all, the pieces are very annoying to put back together.I highly recommend avoiding all Broan/NuTone vent fans. The Panasonic vent fans are vastly superior in every way.
