Let me start by saying this bracket saved my back (and my windows). My old AC unit weighed a ton, and I was terrified it would tumble out of my 3rd-floor apartment. The CAT SO RICH bracket arrived just in time for summer, and wow – it's like having a bodyguard for your air conditioner.

The installation was shockingly simple. No drilling meant no landlord drama, and the adjustable arms (34”-42”) accommodated my weirdly wide windows perfectly. That built-in bubble level? Genius. I installed it solo in about 45 minutes while binge-watching home improvement fails on YouTube.

Sturdiness is where this shines. My 180lb roommate actually stood on it to test (don't try this at home!), and it didn't even creak. The rubber pads eliminate vibration noise – no more rattling sounds when the compressor kicks on at 2 AM.

Two minor gripes: The instructions could use better diagrams (I resorted to interpretive dance before figuring out the cross-brace), and you'll absolutely need weather stripping to seal gaps against bugs. Also, double-check your package for all parts – one user reported missing components.

Pro tip from experience: Use painter's tape to mark your window frame before adjusting the arms. And if you're dealing with an extremely back-heavy unit like my Midea U-shaped AC, consider adding a center support like I did with a wooden trim piece.

Final verdict? This bracket transformed my window AC from a precarious eyesore to a rock-solid cooling machine. At this price point with this level of durability, it's easily one of my most recommended home upgrades for renters or anyone avoiding permanent installations.
