After lots of research, I chose this model.  Dual hose was very important for efficiency and quality of operation.  It works very well.  Immediately cooled my condo living room/kitchen space.  (Would not have expected it to also cool the bedrooms.) Even though it weighs 100 lbs, shipping from the US was fast and free -- and certainly convenient. It came right to my door.  No heavy lifting on my part.  As an urban condo dweller with no car, I could not have picked this up anywhere -- or got it into a standard-sized vehicle anyway.  Only complaint:  it only comes with the window kit, but I need a sliding glass door kit, as I'm sure other users would as well. Some portable ACs come with the door kit.  I will have to have a custom kit made at extra cost.
