This is a Decent easy to install exaust fan, not the quietest fan on the market, but not annoyingly loud like some cheaper models.
great product. I installed this fan in a basement kithen to eliminate odors. Works perfect and has a switch attatched to the fan
My husband managed to put in this vent fan for our bathroom at work within an hour. It works efficiently and was a great buy for the price.
Good little fan for garage or shop. Easy to install. Easy to operate. Helps move hot air out of garage.
The fan works as promised, the only problem I encounter is that the knob that turns the fan on and off is a little short after installation.It is noisy, but it's not meant to be running all the time.
I installed the fan housing into housing that already existed in the wall. It worked like a charm.It turned out to be an easier install than I thought.
