Let me start by saying I've installed my fair share of window AC brackets, and the Kunzye model definitely has some standout features... along with a few frustrating quirks.

The GOOD: This bracket feels like a tank when fully assembled. The powder-coated steel survived a brutal summer storm season without rusting, and it comfortably supported my 18,000 BTU unit (about 150 lbs). The telescoping design was perfect for my uneven brick window sill - adjusted from 4" to 14" without issues.

The BAD: That swivel joint everyone complains about? Yeah, it's as problematic as the reviews say. During installation, mine kept rotating when I tightened the bolts, forcing me to hold it awkwardly with pliers. The metal did bend slightly under pressure like other users reported.

PRO TIP: Use washers between the swivel plates - this gave me enough friction to finally secure everything properly. Took me 45 frustrating minutes instead of the advertised "quick installation."

Where it SHINES: In my RV application (aluminum framing), this was a game-changer since traditional brackets wouldn't work. The rubber boot created a perfect seal against vibrations during travel.

Where it FAILS: If you have vinyl siding, be prepared to drill through it despite the "no drilling" claims. Like another reviewer, I ended up using the spare screws through the boot for stability.

Final Verdict: Would I recommend? Cautiously yes - but only if you're handy with tools and patient with finicky hardware. For simple residential windows, there are better options. For tricky installations (RVs, thick walls), this might be your only solution despite its flaws.
