I used this in the vertical position because I have sliding windows in the bedroom where I installed it. The pullout extensions were long enough to completely cover the space not used by the fan. I did have to drill holes through the extension track on each side and install short screws to keep the the extensions at the length I needed because the track locks provided did not work to hold it from slipping back. Poor construction! Because I have screens installed I needed two wood blocks on the right to hold the fan in place. You can use Velcro or screw them on. The fan then slides in behind them and the window slides against the other side to hold it in place. That was all of the modifications I found necessary to complete the installation.
The fans work really well and I like the ability to reverse the air flow from pushing air out of the room to drawing air into the room.

The fan arrived and installed easily.
My window opens 42-1/2"X12-1/2", so I had to add a piece of cardboard to help block the rest of the opened window. That was simply cutting a piece of cardboard to match the window height and close to the width. The panels on the fan open about 5" on each side, so you have some leeway.
I typically use the fan on "intake" mode to pull in cooler air and push the hot air out the other open windows of my 60 year old house (912 sq-ft) after the outside has cooled below house temperature.
I don't have AC, and during our recent string of four 100+ degree days, the inside temperature would get as high as 85 degrees in the early evening.
My only complaint is that I wish it had a higher speed. It's as if it runs on the low or medium setting of a 3 speed fan.
The fan certainly helped, but a greater air flow would have helped a lot more.
Wider expansion panels would also be a plus for those who windows are wider than 35".
The ability to exhaust or intake without physically turning the unit around is a plus. On some of my hot days, it was useful to vent the relatively hot air out of the room for a few minutes instead of pushing it through the rest of the house.
When i would first turn it on, I'd close the bedroom doors to concentrate on cooling the "living space" & kitchen first. After those temperatures became more bearable, I'd open the bedroom doors so they could start venting too.
Turning on the kitchen vent fan seemed to help a little bit too, removing the hot air near the ceiling.
This will be a somewhat temporary installation. In a few weeks, it'll be removed for the Fall/Winter and not reinstalled until our next hot spell next Summer, IF one occurs.

fan pretty much is ready to go. the built in thermostat is the best feature. being able to adjust either or both fans to intake or exhaust is so helpful when trying to get rid of a strong indoor odor or just trying to get the hot air out and cool air in.

Delivered to home yesterday, placed in a small louvered (1 panel) kitchen (over the sink) window that rolls out to open. We removed the screen and the fan fit perfectly inside the window opening. We opted to set the fan on high with dual exhaust prior to replacing the screen which fit perfectly over the fan. This means we can not reach the on/off switch but we simply unplug the cord from the wall outlet. We plan to keep it going until this heat breaks. Last night the house was fifteen degrees cooler than any night in the last thirty days. I am back today to get another one for the bathroom window, same size and style. Highly recommended.

The fan has been everything we hoped for. It fit very nicely in our horizontal slider. As is usually the case with such fans, the extensions don't fully cover the open window. So we improvised with a piece of white cardboard. This fan is more powerful than prior window fans we have had. It is easy to operation and change speed as well as go from exhaust to intake. It is reasonably quite. We may order some additional fans for use in other windows in our house eve though we probably won't install them until next summer. Overall, good quality and operates well.

Rated 3.0 out of 5.0 by JMS630 Good purchase with some effort
The fan is only a $50 item, so it can't be all that substantial. Luckily, it's effective at drawing in cooler air which would otherwise seemingly sit outside.

I love how you can reverse the fans seperatly. It's kinda loud on high but nothing compared to other cheap brands. In all a great buy.
