This is my second unit. The first performed so well that I bought another one. It is quiet, energy-efficient, and remarkably effective. My living space is 1,000 square feet open plan, with 12-foot ceilings. The first one cooled the entire place to 74 degrees when the outside temperature was over 100. That's more than twice the capacity LG claims! I decided to get another one as a back-up, in case the Northwest experiences another heat dome like the historic one in 2021.  Great product!
