"If you like a buzz saw"
The fan definitely makes the room cooler, and it fits my windows. But after an hour or so, I can't take the sound anymore. It's like having a buzz saw or a squadron of fighter planes just outside my window. Even on the lower speed, it is unacceptably loud. Much louder than an A/C.

"good for price and size"
i chose this fan because it was the only one small enough for my attic window. it does the job. it fits the window. it's not, however, very powerful, and it's REALLY LOUD!

"Holmes Fan"
The Holmes window fan was not what I had in mind. I tried to return it only to find Amazon did not take returns on Holmes Fans. My fault, didn't read return policy for Holmes fans. Beware of that.
Holmes would not let me return it to them for a refund. Fortunately, Amazon allowed me to return it to them if I paid the shipping. Then they credited me for the shipping cost also. So, thanks to Amazon, it worked out ok for me in the end.

"Holmes Window Fan"
Nice product,PROS: easy to install,built-in extender panel CONS: Reversible Air FLow control is not automated"its manual you have to reposition the fan again. 3/5

"Not bad for a $16.60 fan!"
I bought this fan at Walmart. In fact, I bought two window fans because I didn't think this fan would be worthy. I got home that night around 11:45pm. It was 81 degrees in the house, but outside it was nice and cool. I set it up and it really pulled the cold air in. The temp dropped to 73 with the fan on. Nice.

My windows are new casement type windows and this one fits perfectly. It has a extension that will make it longer and at the other end, there is a pull out extension that will make it even longer.

I'm returing the other one which is a HAWF2026 - it just doesn't have the extra extension and the adjustable one (doesn't have any of them).

I really wished they put a more powerful motor in these, but for the price it's not bad. If there is a more powerful one I'll buy it. I'll give it a 4 star because it's not powerful enough, but it works great!

BTW, I do have AC in the house, but why use AC when the outside air is chilly already!
