We bought this a month ago and it works great!  It cools our small bedroom and bathroom area in our house very quickly.  We also use the "fan only" for white noise to sleep more soundly.  There is a more high-pitched sound that is not very pleasant when the cooling function is on, but we don't need for the cooling to run very much.  And, it's not a bad looking unit.  There are SO few choices when it comes to slider/casement a/c models which means that they are also MUCH more expensive than similarly-featured "regular window" models, but, nonetheless, I'm glad we purchased this air conditioner.
