This is a very quiet unit, and has good reviews. I have one and it is the best windows AC that I have used. The 8000 BTU unit normally sells for $360 or more. The 12000 BTU model has dropped to $266, which is way below the previous low of $430 according to CCC. Compared to the normal $470 price tag for the 12000 BTU unit, this is a saving of >$200.
There are still some units in stock at the moment. Not sure how long this price can last.
