Awful, middle fan doesn't work, and the other two fans (left right) make loud noise, and is much weaker, awful awful awful.

Although the product reports that it is able to be placed in vertically, it is only for very short vertical windows. The fan is useless to me.

Worked well for a couple months. Motors started burning out after about 60 days.

Its ok for a bedroom window by your bed but nothing else. The "thermostat" switch does nothing to my knowledge and it doesnt circulate the air nearly as well as a fan that size should. For three blowers, this sucks. Id send it back but they want me to pay to send it back. No thanks.

A gutless wonder. Doesn't suck much of any air, at least in our basement situation.

It failed after less than a year of modest use.

This fan does not work well at all! I would never purchase this again!

Dont buy this fan!!! 2 of 3 blades have stopped working after only 2 months.

Overall, this fan was exactly what I was looking for in my space. However, once the third blade got activated it rattled. So basically I can only have it on one fan. Might have to take the whole thing apart. Frustrating. The worst part is I can't return it. Buyer beware
