Bought this in July of 2023.  It's now Jan 2024 and we're delighted with the product.  Cooled our 350 sq ft bedroom nicely.  We just started to ue the heating at night since we have no heat in this addition; it works wonderfully.  Not noisy in my opinion.  You hear it turn on when it needs to, but nothing to warrant major concern.  Had to buy a drip pan to place the unit on for the condensation line didn't reach or bend properly to anything and we couldn't get it out the window.  The pan works fine, you just have to soak out the condensation from the pan every couple days.  Love the unit and would buy again.
