I bought this fan because it has a fan blade design which are used in quiet fans. It is very quiet, and makes a low tone when running, versus the whine of other window fans. It's low profile allows you to see out of your window more instead of blocking the view, perfect for spring and summer. Since it is small and light, it is easy to insert and remove from the window, something that's hard to do with a bulky fan.
Notes: It is billed as a whole-house fan, but it doesn't move that quantity of air, if it did it would have to be noisy. It should be marketed instead on it's best points, quietness and low-profile. One of my new outlets seemed not to want to connect to the plug, so it looked like it was plugged in but no power was received. I blame this on my outlet rather than the fan, as it works in my other outlets. It comes with a sturdy side extension built-in, and two extra extensions to add on the other side. One extension is hidden in the foam packaging, so look for it before you throw the foam away. Each side has a rubber seal that can be inserted and removed on the extensions, so you can put it wherever it needs to go. Overall this is a high-quality fan and I'll get more for my other rooms. I'm quite impressed with this one.

Works as described...more or less
So I got this window fan for my office. These space has my video games system, PC, etc. I work and game here. As you could imagine, running all of these electronics produce a lot of heat. I was looking for something that could exhaust some of this heat to cool the room down without having to use AC. This room has its own AC unit, as it's an add-on room and not originally part of the house.Out of the box, the unit is new. I address this because some of the reviews cite damaged products or used products. The fans spin fast. With that, there is some noise but it's not noise you couldn't just tune out. It's regular fan noises you would hear with any fan. It blows hard/fast, which is good.You can use it either to blow air from the window, or flipping it over, you can exhaust air out of the room. Biggest issue with this is the design of the unit. The main part is off center, which means it only sits comfortably in the window in one direction. You can see this in the pictures. Once I flip it around to use the exhaust, it's no longer flush unless I take off the screen, which I don't want to do.This unit extends. However, the max length is 3ft or 36inches. Unfortunately, my window is 44inches long. And that is my bad for not looking at that before purchasing. The cable is 6ft long. Knowing this, I still set it up to at least attempt to exhaust some of the hot air to cool the room. The room was 91F and after about 1 hour of running, I have a temp of 90F. I have two other fans blowing/circulating air as well.It's a strong fan, but it doesn't seem to cool my room effectively. Keep in mind though, that this fan isn't covering my whole window, so I don't know if that has anything to do with it. It might work better if you're using it to blow air from the outside as opposed to an exhaust fan.Also the sides do not sit flush to the window closing itself as you can see in the photos. The extension lock is only on one side so the other side kind of hangs there and tries to retract back into the unit. Should probably have a lock on both sides to avoid this.Unfortunately, this unit doesn't work for my needs so I will be returning it.
