To blow air out and to inflow air in.

Last day to return Feb. 8th. One fan dies Feb 14th. March 26th fan is basically useless.

stop working after 1 month. worst ever. wont ever buy again.

2 fans stop working. work less than half year. Already recycle it!!!!

Started making noise about three weeks in getting worse

Failed in 2 months.

After four years of summer use, two of the three fans stopped working. A shoddy product.

I’m very disappointed with how strong the fan is. I expected a better fan

Both of the blades are not working a no one can help me even tho i have the extended warranty.

It is hard to put in the window. I have had it fall out as I was trying to install it. The air current it creates is not sufficient, even with a total of 5 fans blowing through the house with the direction of the wind. Very disappointing. A waste of money. My 20 year old fans create more air flow than these.
