I like the fact that there is a grate at the end of the window hose so you don't necessarily need a  screen to put it in your window. However it does not cool down 700 square feet as well as it should. I have a 620 square foot apartment so I thought getting this I would be good for the summer. It cools down maybe half of the apartment and I have fans blowing the air into different areas. Its bigger then I expected too but that's no big deal for me.
