Took 2 minutes to put together and install in my window, i didnt even need either of the supplied adapters, i am using it as intake for my portable air conditioner and the duct hose that came with my AC unit was able to screw right onto the duct kit port itself. 100% satisfied with yet another AC Infinity product, highly recommeneded.

While I have nearly the same thing for a floor AC unit this still would only be helpful in warm climates.

If a insert similar to this design could be made insulated or even just sealed against a open window I believe it would benefit ventilation needs for people in colder climates.
