Okay, so my original LG window AC remote decided to play hide-and-seek permanently. Found this exact model replacement and IT WORKS PERFECTLY!

No complicated setup - just popped in AAA batteries (not included, FYI) and it instantly synced with my LW1516ER unit. The buttons feel sturdy and responsive.

Pro tip: If it doesn't work at first, check the battery spring connection like the listing suggests. Had to gently pull mine out a tiny bit for perfect contact.

Special shoutout for helping my elderly neighbor too! Her mobility issues made manual controls dangerous, and this remote gave her back independence with temperature control.

Only dock half a star because the packaging could be sturdier - but hey, it arrived intact and that's what matters!
