Review: Works Perfectly for Casement Windows – Great Value - This kit did exactly what I needed it to—and at a great price. Other solutions like custom plexiglass were going to cost hundreds when I checked, and even a DIY approach would’ve been at least three times the price of this. I had it installed and my portable AC exhausting out a casement window in under 15 minutes. The zippers and seal feel secure, and it’s held up well so far. If you’ve got casement windows and need an AC venting solution, I highly recommend this kit. It’s simple, effective, and way more affordable than the alternatives.
Review: Works but looks terrible - This allowed me to use my AC but it looks awful and will need to redo the Velcro strips every summer so I can close the window in the winter.
