It's a good unit overall.  Looks nice, gets very cold quickly.  What I don't like is the fact that it has vents (openings) on top of the unit.  I didn't know this prior to purchasing.  My old unit of a different brand (had for 29 years, still worked well) didn't have these openings on top; just vents on the sides and back.  Unfortunately, with the openings on the top of the unit, it allows all sorts of debris, bird droppings, and when it rains heavy, look out.  It leaks inside from the bottom, and the a/c gets loud and you can hear massive amounts of water sloshing inside when you put it on.
