I like it but weather has been moderate so far and have only turned it on to make sure it operated.  One big issue I had was the exhaust hose is heavy so it keeps pulling hose unit out of window.  Don't want to peel & stick foam as indicated as I want to move where needed  when temps are over 100 for long periods & to take out to store after summer.  Need some type of lip on window piece to keep into place better similar to a window a.c. unit.  Also have no idea how to use casters, 4 wheels but 2 casters.  No pic as to how place them, don't they make it lopsided & uneven.  My floor is laminate over concrete unit was LOUD during operation but cooled several degrees very quickly.
