I've had this unit for a little over a year now and I'm pretty happy with it. My room is cool and comfortable in under 30 minutes. It's easy to use and doesn't look bad in the window at all. 

I give it 3 stars because recently, it developed a mildew smell and I can't seem to get rid of it. The manual instructs not to take it apart. I called and the best solution they had was to use bleach. It's a temporary solution at best. It lasts about an afternoon but comes back the next day. Nothing shows at all how to clean it and it's embarrassing to have anyone over when my room smells like I don't do laundry. If 5 stars if I can find a solution though.
