This little guy really cools my apartment off well during what has been a scorching summer in Chicago. My only complaint is it can be a little noisy and rattly, but I honestly think it could be due in part to my windows. I live in a walk up built in 1895 with original windows and it's hard to get a tight fit on the AC so on occasion I am awoken by the window and AC rattlinga bit. It came with lots of insultation materials and strips, so after stuffing some of that into lose spots the rattling has greatly diminished. For the price I would definitely recommend this product. I use it in my bedroom on low and it cools excellently.
