The hose attachment and window vent for this unit are definitely better than our old one was. But they are still a bit flimsy in my opinion and a bit hard to get situated correctly in the window. Otherwise this unit is working great so far. Not too loud. Makes the room comfortable. We have not had a real hot day yet (above 90) but it definitely performs well in the high 80s degree days. Update: it worked well all summer even the hottest days.
