Okay, so I finally got around to installing this wall mount connector for my portable AC unit, and here's the real tea:

First off - MAJOR props for including both sizes (6" and 6.5") because my hose was being extra and didn't fit standard connectors. The silicone cushion ring is a game changer - no more hot air sneaking back into my room like an unwanted ex.

The installation was... an experience. The included hardware made it pretty straightforward, but PSA: those screw holes are dangerously close to the edge! I nearly had a DIY disaster moment. A wider flange would've been chef's kiss perfect.

Love that they included an off-season cover - it's like giving your AC vent a cute little winter hat. The ABS plastic feels sturdy enough to survive my questionable handyman skills.

Pro tip from my fails: measure twice, cut once. And maybe keep some weather stripping tape handy just in case. It's not flawless (why does the hose screw on counterclockwise??), but for the price, it gets the job done way better than rigging something up with duct tape and prayers.
