Disappointed with this unit. Cannot provide a review on its cooling or evaporative abilities due to continual issues with the exhaust hose. On other portable air conditioners I have owned the hose twists onto screw like threads on the plastic connector or it has clips to hold it in place. On this unit there are 3 level threads (not screw like for twisted threading) and the hose does not stay attached to the plastic connectors. It detaches and then the hot exhaust is released into the room. I am very disappointed with the poor hose design given the price of this unit. We have had it for 5 days and have been unable to really use it because we are constantly fighting to keep the hose secured. Debating whether to pack it up and return the unit or make an attempt to hold it together with HVAC tape, which may work but feels like we shouldn't have to jerry rig together the hose on a brand new unit.
