Review: quality of materials cant be beat - this is hands down the best window exhaust for whatever need you have for it. Does'nt matter 6" or 4' you are getting the best i work as a lead maintenance for a company and in the spring time i put in over 80 AC units and this one is so easy to install and looks and performs great i use this at home and i have asked for the spring time to swap over to these so as i need them even at work now im gonna have them thats how much i like this product nd if any other Product coming from AC infinity there compotition cant even compare to their products all the way down to how it is Packed AC infinty has one up on all the rest
Review: Great option for venting hot PC exhaust to window - I’m using this to connect a 6in flexible duct and inline fan to exhaust a high performance PC. The PC and graphics card put out some major heat when the room door is closed. I put the intake fan next to PC and when running triple A titles, the heat goes out the window and I don’t live in a sauna anymore. Works perfect for this purpose and I am not paying for an extra window AC unit. That would probably work as well, but spending more electricity to cool a room seems less efficient than just exhausting the hot air out with a fan.

### ⭐⭐⭐⭐ Works good
*by R***O on June 25, 2023*

Its not perfect. My major gripe is all the thick plastic bags for stuff. That could have went into making nicer wing nuts/assembly hardware. Smells like the free toys included with fast food kids meals from the 80s/90s; in otherwords smells like happiness meals. Thats a star alone right there. Your window bug screen setup might need adjustment / cleaning depending on an intake/exhaust setup. Reguardless I would imagine crap on the screen either getting sucked in or pushed around depending on your window design, perhaps to the point of being forced out from too much outward airflow; so I think a decent sized duct run from the window to your fan is nessary to prevent a lot of problems stemming from bugs, rain and so forth and if your window opens horizontially then you pretty much have to put the outlet on the bottom for stability reasons.
