Rated 5.0 out of 5.0 by Solo Super handy fan/extractor
It's very easy to set up. Very versatil. I use it in a Food truck, where I need to remove it to drive, and re-install it once stationary, and even then it's very practical. Works great. I have use for it, both, bringing air in, and also extracting the air out, depending whether it is just parked, or being occupied. I've had these units before in an apartment window, and it also worked great there, removing stale air out of the bedroom. By using two units in opposing areas of the dwelling (one out, and one in) you'll be able to have a steady movement of air current throughout the whole area in between. I just love those units.

Very sturdy construction, but light weight. Thin enough that I could leave the screen in place, so no bugs. Incredibly quiet and unobtrusive.
I'm using it as a vent fan for a bathroom, so the small size is a plus. It even fits behind the plantation shutters! I love the 'exchange' setting which draws air in with one fan and blows it out with the other.
Installation took 3 minutes max.
You won't go wrong with this fan.

Received the product on 4 May 2016. I was extremely disappointed when I tried to install the fan. The bottom extender lock failed to release and hence I could not install the fan. The item should never have been sent out from the factory as it is very easy to check whether the lock works - just pull it down.

This fan is quiet until it's turned to the high setting and even then it's not horribly noisy. Although it doesn't expand to fit my window, it moves the air well and that's what I bought it for.

Rated 5.0 out of 5.0 by oregonhomeowner Really good fan at a great price.
The fan is made of lighter grade plastic than the higher end Bionaire and Holmes fans, BUT its motor seems more powerful. It runs quietly, is simple to operate, and moves a lot of air, AND it costs about half as much. No frills but a fantastic value.

Rated 5.0 out of 5.0 by samiam Glad my local cust service guy recommended
Glad I took his advice.
I bought this for a number of purposes from 1~cooling, to 2~disperse cooking odors, and to 3~protect from local pesticide spraying by shutting myself indoors using the dual exhaust setting.
Word: purpose #3..I made the mistake of turning the Dot dial all the way up which, even on full exhaust setting still sucked in the scent of pesticide spray as they rode by. I turned it down to the 3rd Dot which I should have done in the first place.
The cooling feature is MAGNIFICO, quiet and VERY effective for cooling. I detest air conditioners, depending upon cross-currents previously, but with the pesticides I can no longer do this without this smarter alternative.
Q&A section answers all questions about jury-rigging, nothing's perfect but worth it.
Very happy I bought this fan, and since it can't be undirtied from dust and dirt this item is inexpensive enough to replace when the time comes.

Rated 4.0 out of 5.0 by Oti Great Product, Would Purchase Again, Better than Competing Products
We use the fan to cool our living space in the evening and night during the summer.
1. The unit was far better than we expected in terms of build quality and function.
2. We were so pleased with the extra window closure panel that extended the range of the built in, adjustable width/ height adapter.
3. The speed adjustments, reversing of the fan rotation direction with a switch and bi-directionality (one exhausting while other was blowing inward) are great. While the thermostat function allows one to set a trigger level for the fan operation, a feature that we don't use since in the day temperatures can be over one-hundred Fahrenheit and leaving the fan in the window would not be sensible because the incoming air through the fan openings would heat up our living space beyond the comfort level.
More About How We Use The Product - by way of explaining why we wanted it and our evaluation
What we do is wait until the evening, outdoor air is equal to the indoor temperature, then we open the window, install the fan, set the speed to max exhaust speed through our living room window and then open our bedroom window to cool our bedroom first and then more slowly the living room since the bedroom air coming through is warmed by the bedroom itself before reaching the living room.
We get as high as a twenty degree differential between the indoor and outdoor temperature during the day by shutting off the fan in the morning when the indoor/ outdoor temperature differential is zero (same level) and we remove the fan and close the window until evening when we begin the cycle all over again.
Installation Considerations - Our Experience with the type of window in our house
For our use, where we have sliding, wood framed, thermopane windows, where the depth of the window assembly is less than four inches from inside to outside, the fan body depth exceeds space between window sash and the window screen, so the fan unit cannot be installed with the screen in place.
Not wanting to remove the screen, we built a wood frame surround (box) to mount the fan offset, away from the screen. The window now closes against the frame and small wood blocks on the outside of the frame lock into the window groove to keep the fan from toppling out of position and falling. See Installation Photo
Tuning Up Fan Performance
Now a word about the fans power - air moving ability. We noticed that the unit was not able to match the air flow of our small, 40 watt box fan which we bought in Malaysia while traveling, and we use around the house via a 220 volt travel adapter. It was this fan that we were replacing for window use.
We were incredulous that our new twin fan unit could not keep up with our old mini-box fan. So we measured the fan face diameters for the new unit and the old one: the new is twin 9 inch diameter fans and the old was only 12 inches (we brought this diminutive baby home in our suitcase). Actually the new fans have more square inches of flow area than the old 12 mini-box fan (pi r squared x two fans vs pi r squared for the single fan).
So, why the poorer performance. And then we noticed that, while the new twin fans had nice aerodynamic blades, they were something like 10 decibels more noisy. Then we took a closer look through the grille of the new fans: They start off great with a ducted fan design, so why the noise and lower performance???
Closer examination shows a real boo boo on the exit path for the fan air: The air exits the fan into a non ducted cavity and the air path is not aligned with the fan axis. Not only that, but the exit grille is not circular, not aligned and smaller in area than the fan face diameter: naughty, naughty. This causes turbulence, loss of efficiency (lower performance) and noise generation.
We love this new fan pair though and the manufacturer almost got it right . . . so we just inscribed exit circles on the exit side of the case in a larger diameter, but aligned with the fan axis and cut the plastic away with a utility knife. We then took a bit of aluminum sheeting from a dryer vent (purchased from Home Depot) and completed the original plastic duct to conduct the air smoothly to exit the case. Since the fan exit faces the window screen in use, we did not make a new exit grille.
Wow, now the noise is reduced and the fan efficiency has increased majorly so we equal or exceed the old mini- box fan.
Our house is cool all day - see above technique description - and we are very happy with this fan unit, even though there were some practical issues in both fitting it into our average, normal wood framed sliding window and in the poor fan exit path design.
All in all, a great unit and it works well even though the manufacturer missed it a little it was retrievable:
We would recommend the fan over similar designs that really have less features and function.
