Honeywell Twin Window Fan

ordered this fan to use in my bedroom window at night.  the fan part is nice and works as described--although i wish the low setting was even slower.  the main problem was the side extension panels that are "adjustable" so it will fit in your window---well the solid plastic part that attaches to the sides of the fan were too long---with only 1 attached the fan wasn't wide enough!!--and with both attached they were too wide.  tried every combination--extending the adjustable one out all the way---pushing the adjustable one in all the way--all to no avail----it just didn't fit--sooooo---i used a saw and cut  the non-extendable one in half  and viola---the extension panels fit.  accordian style panels would have been sooo much easier than the solid panels.  other than that the fan works very well and after solving the window problem i am very happy with my purchase.    

The fan works great 4 stars (knobb are difficult to pinch and turn) but the  1  star is for the lack of available parts for this fan. With the extendable side panel it's too short to fit my window and with both panels it's much too long. I wanted to get another extendable panel but I guess I'm just going to have to cut the fixed panel down so it fits.

Very useful to move air out of the room, or to bring cooler air into the room.  I have my fan in a bedroom that is a considerable distance from the rest of the house and it greatly inhances air flow.
