This is the 5th unit of this type I have purchased in 6 years for different rooms/homes.  Goods - It cools well with a coil temp of 40-48F (laser IR temp gun) and it is a lot quieter than my others.   Oddity - Louvers.  Rotation for 1st week went from 'closed' to blowing on the floor???  Every other unit I have blows the cool air 'up' whereas this one blows it down. Very odd and not where I want the air flow.  I resolved this by removing the upper louver and stopping the 'swing' while the other 2 were closed.  Today when powered up, the 2 louvers rotated from floor to horizonal.  (Still not 'up' so I l am leaving the upper louver off.)  If not for this issue I would give it 5 stars.  Still a very good unit at a very good price.  I would not hesitate to buy another if needed.
