Summary: The fan rattles when it starts up but goes away once it reaches its maximum rpm and starts to cool.
Pros: Cools a 10x15 room pretty well. Not super fast but reasonable time (I'd say about 30mins to bring it around low 70's).
Cons: The rear of this unit does not have drain holes. I know they say don't drill any holes however, if you live in a very humid area then you may just want to make a very small hole in the back to allow the water to drain. Or tilt it a little more then recommended (would not advise doing this unless you are very good at it). So you will start to get water buildup quick on a humid hot day.
Summary: 1. The knob for cooling adjustment is very touchy, if you set it too high (anything above 4) the cooling coils will freeze over after a few hours.
Pros: The air conditioner is small and it can cool a small room but those are really the only pro's to it.
Cons: Unfortunately there is a laundry list of complaints that I have with this device, and after owning it (and a few others of different brands for near the same amount of time) I can give a decent description as to why:
