After testing this window AC bracket for a full summer season, I can confidently say it does its main job well - holding heavy AC units securely. The powder-coated steel feels industrial-grade, and the weight distribution truly takes pressure off my old window frames.

The installation process was mostly straightforward, though I hit a snag with the built-in level (mine also arrived dry - seems to be a common issue). Thankfully, my phone's level app saved the day. Drilling into the sill took some elbow grease, but avoiding exterior drilling was a huge plus for my rental situation.

Where this product shines is its versatility. The adjustable arms accommodated my thick 9" window frame perfectly, and it's currently supporting a bulky 8K BTU unit without any sagging or creaking noises. The weight transfer system works as advertised - no more worrying about my window sash bearing all that weight.

However, the included instructions are laughably bad - tiny font, confusing diagrams. Like another reviewer mentioned, I'd recommend watching YouTube tutorials instead. Also be prepared to supply your own screws if any go missing during shipping (happened to me too).

Despite these quirks, for under $50 this bracket delivers where it counts - sturdy support that doesn't damage your window structure. Just approach installation as a weekend project rather than a quick fix.
