Amazon Basics Window Fan with Manual Controls, Twin 9-Inch Blades

This is a great window fan. Being able to switch fan direction for each fan individually is nice. One downside, the adjustable sides dont extend very far and they want to close back in. Other than that, the fan works great.

Installed it this morning and found two annoying things about it: 1) at the low and medium fan settings it emits an rather loud hum that makes me not want to use those two settings, and 2) it doesnt work all that well at the top of the window (upper sash) due to the control panel being slightly crowned and not on the same plane with the top of the unit. On HIGH the hum disappears but the fan noise is more than I would want on a regular basis. Overall an OK unit but not quite what I was hoping for.

Very easy to use and set up. Flexible option to make use on table or install in window. Good power and quiet motor.

Turns on. Has multiple speeds. IS reversible by switch, which is why i bought it. But DOES NOT actually move ANY AIR at all. Blades spin. No air movement. Returned.
