Bought this to cool down my 1300 sq ft living room and this thing has amazed everyone on how quiet and powerful it is.  In the past years I've had 2 portable air conditioners (18,000 BTU) that couldn't cool down the same space. The dual inverter technology is a game changer; because it's variable on the power load it doesn't trip my house breaker when it turns the compressor to max cool. This is the closest thing to the performance/efficiency of a mini-split unit without the hassle of installation! Highly recommend! 
Pros:
Extremely Quiet
Powerful (Cooling my 1300 sq ft area)
Great with homes with bad power and trips breakers
Modern look
Cons:
Size( Can't blame LG.  Condensers and evaporators need surface area of they want to be effective)
