I live in Hawaii so I didn't even bother returning it due to the insane shipping fees but this is the weakest window fan ever. I guess the size is small enough for it to be easy to put by any window but it really doesn't blow enough air.

Good, but not strong enough

Doesn't have enough power to keep the hot out but looks nice

Its much smaller than the picture. Big disappointment

I gota say I really liked this product but one of the fan motors already burnt out and it's only been a month totally sucks

After using this fan for two summers, I cannot say it makes much difference for intake or exhaust. We use the fan in a small 12"-12" bedroom/office. The fan does not seem to move enough air in or out to help the temperature in the room. Even with the best conditions, such as the connecting hallway (and outside) being 10 degrees cooler, this fan just does not move enough air into or out of the room to be effective.

Ehhh... Its a 3 fan window fan, but not all 3 fans spin at once unless its on full speed. For the price, there should have been a speed controller in the circuitry. I got it to ventilate a studio apartment while cooking.... It barley makes a difference. Might as well just open the window without a fan. lastly, It is not very long/tall and the included extenders don't extend much The fan itself is too short to fit the window I bought it for, and needed some wood cut to seal it off.

mostly garbage. two of the motors failed within few months of use. the design is nice and sleek, but the rest, including the controls is very poor.

great for fitting into old windows, but too weak I would return but I waited to long :(

Sad to have only 2 of 3 fans working. The 3rd fan never worked...was dead on arrival. It's not pulling a lot out of the room. I am looking for another brand with a better product as I do not recommend this one.
