I like that there is a grate at the end of the window hose so you dont necessarily need a screen. However it does not cool down an entire apartment. I have a 625 foot apartment and this says it can cool off a 700 foot apartment. I thought it would be stronger since my apartment is smaller then what it claims to cool down for but it does the job. I use fans to circulate the air through the rest. I also love that it has an app and I can turn it on when Im not at home!
