One of the most important thing for me was how well it would fit .It fits my window frame like it was custom made.Controls are user friendly.the fans are quiet.Fan power is good.I wish in came in black is my only con.

Excellent product for our tiny house.

I ordered this unit specifically because the Amazon page -- both in text and in pictures -- stated the fans side panels expand to make the overall length of the unit 37 inches, and could be set to inflow or exhaust. It only expands to 34 making it useless to me, and the exhaust mode is pitifully weak, again making it useless for my purposes. And seemed rather flimsily made to boot. Returned it immediately.

Easy to install in window, has been working great for the past few weeks. Love the different speeds and remote.

Works good.

This ventilation fan is my favorite one I have ever used, especially when I occasionally need to change the outside air at home. It makes me feel very comfortable to use, and the sound is also within the range acceptable to everyone in the family. The cold air mode can also quickly achieve a cool state for myself, which is great

Louder then expected...but easy to use and put up... overall I liked it!!

Nice y

I bought this fan for the kitchen in the apartment where my mom lives. It has three speeds to control. It can exchange air and make the air circulate. Works great so far. My mother is very happy with it.

It has a really annoying 120hz hum. I wouldn’t use it wherever people are located which is kind of the point of a fan. The noise is louder than the sound created by the fans themselves. Otherwise the remote is nice and the ability to change direction and intensity. But the noise is a dealbreaker
