Why I’m returning it

It looks nothing like the picture and it’s not even white, it’s grey and has yellow tape inside where the blades are. The high speed doesn’t feel high and the low speed is super low.


Unexpected value!

I bought one of these from my local Walmart about 4 years ago, and it's still going strong. It cools a small to medium sized room all by itself, and the 2 speeds are quite adequate for the job. I moved this year, and will be buying another to use in a larger livingroom, and I expect it to work well. I use it almost every day in the summer. I have a friend with an air pressure tank, and this year I will be bringing the old fan for a thorough cleaning. Since it is a few years old, I plan on doing this plus adding some Mystery Oil to the motor, though I dunno if it will be before or after the summer season. To sum up, it works *SO* much better than I thought. I had bought another brand the year before I got this one and by the end of the season it was DEAD; this one is going into it's 4th year with little care on my part. Moves are well for it's size, is fairly quiet (but does make noticeable noise) and lasts longer than I thought as well. To me, an excellent and unexpected value for my money.


Dual Blade Twin Window Fan

First the price is right, second this fan only has two speeds lo and hi which is perfect for where and how i wanted to use it in a kitchen small window to pull cool air in when the sun is not on the back of the house. It works great i wanted lo power reliable construction so that it can run great part of the day, and i also wanted lo power because i did not want it to sound like a exhaust fan wanted no more them minimal amount of noise from it this fan is quite. Assembly really easy you add one piece on the side boom its ready for the window the other side is accordion style it has two clips you pull out and stretch to fit your window length. Also the top has two raised bumps so you can bring the window down to catch it. Works perfect for what i needed hope this helps you make your selection.


ok fan, but nothing great.

Biggest issue I have with this is that the "slot" at the top where the window closes on is too small, so instead of closing against the body of the unit, it rests on the round slot walls. Doesn't move as much air as a box fan, but it is a little quieter.


It is loud, but it works.

It is loud on low. It is so loud on high, you will not want to be in the same room with it. :p That said: It works pretty well once the air starts moving through the house. I put it in a back bedroom and raise the window a bit in MY bedroom. It draws in cool night air. It was worth the money - even with the noise. ;)
