Quite fine. I was a little bit afraid that it wouldn't move a lot of air, as people have been posting- but it does pretty well for me, and it's much less intrusive than rigging a box fan into the window. The plastic bits that sit on both ends are a bit misleading- they don't extend very far outwards. Make sure the window you're sticking this thing into isn't much more than 4 feet tall.

Not very strong motors for fans.

I used to live in a room with no AC. It sucked. I installed a ceiling fan, didn't help much. I ordered this fan and put in the window. It did wonders. It will blow air in, bringing in the cooler air from outside into my hot room. I think, even without the ceiling fan, this little guy did the trick. Thank you for saving my summer.

It is quite and fit perfectly with my window. You will have to oil the fan bearings once a season. Don't buy if you aren't capable of doing that.

This is a good basic fan. the temperature control is a little weird but works. Would have liked to have had a switch to reverse the flow but flipping the fan works too.

Good item, but I have found that the "temperature control" function really isn't all that helpful in a real world situation. Save some money and just go with the standard manual control version.

Works great. One gripe is you must cycle through the whole menu to change one setting. A remote would of been awesome for this.

Great fan! Doesn't take up a lot of window space, and moves a lot more air than the Bionaire dual-fan window units. It is also whisper quiet compared to the dual-fan units. As my older dual-fan units wear out, I will be replacing them with more of these.

I do not have a bathroom fan in my apartment, this fan is small and what I wanted. It is quiet enough, but it just doesn’t have enough “power” to keep the steam from getting on the walls and streaking. It does however, keep all bathroom smells away.

Love my little fan. A bit smaller than I anticipated. We ordered it on May 30th but it didn't arrive until 6/10 so we are pretty disappointed with the shipping speed here. Product itself is great though.
