Just installed this window AC bracket last weekend and overall I'm pretty happy with it! The indoor-only installation was a game-changer since I didn't have to mess with exterior drilling. Took me about 30 minutes while watching TV - that's how easy it was.

The built-in bubble level is GENIUS. As someone who can never tell if things are straight, this feature saved me from having a lopsided AC unit. The adjustable arms handled my thick 9-inch window frame perfectly.

Sturdiness gets an A+. My 8K BTU unit feels rock solid - no wobbling even when the compressor kicks on. Definitely takes the weight off the window sash like promised.

BUT... the instructions might as well be hieroglyphics. Thank goodness for YouTube tutorials! And those included screws? Way overkill - I ended up using my own shorter ones that wouldn't poke through to the outside world.

Pro tip: Check all hardware before starting. My package had some missing screws (common issue according to reviews). Luckily I had spares, but this could ruin your weekend project if you're not prepared.

Despite these quirks, for $30 this bracket does its job well. Just be ready to improvise a bit during installation!
