lasted 1 year from the time of purchase

Noisy and one of the blades has stopped working. I haven't been using it a month yet.

did not function out of the box switches would not allow all three fans to work. just poor quality control.

doesn't fit window right

DO NOT BUY. Works great at first. I bought 4 and one by one the blades went out. within a year in a half, I have four fans with only a single blade working in each fan. What a waste of money.

One of the fans stopped working today...

Only worked for 4 months. Only 2 of the 3 fans still work. Very unhappy.

This fan was amazing at first! It's been 2 months and the middle fan quit working all together which i am finding is a theme throughout the comments. Also, the low setting stopped working this week no matter what I try!! I would NOT buy this fan as there is no way to contact the seller or do a return. Not satisfied !!!

very disappointed. 1 of the 3 fans stopped working after only a month. Also the amount of air that it moves is almost not worth it unless you are sitting right next to it even with all 3 working! currently looking for a better window fan.

Barely blows air
