These things are pretty neat, because you don't have to sacrifice a window for them, as you can see. The exhaust hose needs about 3" of clearance in any window, and the unit itself sits on the floor. Verra practical if you're not quite sure where exactly you want to cool on any given day.
I hooked it up about an hour ago in the bedroom, and here in the front room it is already nice and comfy. You'd think I would hook it up in the room I'm in, but that would be far too logical. (See, I have a working window there, but a relatively clean office space here. Maybe tomorrow I'll move my office.)
