Installed in a 120 sq ft bedroom, it works so much better than my old portable which was much more powerful.

For the reviewer who thought bugs and whatnot could get through the unit: Yes, you can see daylight through it, but of you look closely there's a block of styrofoam insulation that seals it off, but is somewhat translucent so you do see daylight through it.

For the reviewer who thought he needed to drill holes in the bottom of the unit to let the water out... facepalm 

Also I love eco mode, I like not having the fan run constantly and it keeps the room very comfortable.
