It doesnt throw much air as advertised.Sorry I bought it!

Blades came warped, and one bearing is out of balance causing it to be very noisy.

Have had for about 6 months and the motors started making a love Squealing noise took apart oiled it up it stopped for a little and started again 2 out of 3 of the motors ar doing it now.

Not quite large enough for my window, and I can't order more extenders from their site.

Disappointed, really doesn't provide cooling air

One of the fans stopped working after a year, by far the worst durability of window fans I've owned

I used this product for bathroom ventilation. However to my surprise, two of the three fans inside the product stopped working after 2 months.

weak fan. weak fan that I don't even use anymore

Two of three fans quit working, one at a time, after the fan was not yet 6mo old.

Loud, a lot of vibration, doesn't move nearly as much air as the 2 blade units I have in other rooms.
