Title: Okay, but doesn't cool like a 12,000 btu window unit
Review: I purchased this a/c a few days ago to cool off our family room (approx. 140 sq feet) with adjoining kitchen (approx. 120 sq feet). The description says it can easily cool up to 400 sq feet; however, I think it falls extremely short. It was about 92 today (very hot for Seattle) and it took all day just to get below 80 degrees in these two rooms using this unit. My recommendation is to use this for only one room, not to exceed 200 sq feet, e.g. a bedroom or office. Don't believe the hype that a portable 12,000 btu unit can perform cooling comparable to a window unit. This one is probably very good for one room, but struggles terribly to cool over 200 sq feet. I do like the fact I don't have to empty the water.
