Just received yesterday and I set it up this afternoon. Pretty easy to set up, nice remote control. Air louvers move up and down to distribute air better. Lots of control options. Attaches to window pretty easily. Blows very cold air. And blows it quite adequately, on even the lowest blower setting. And when on that low setting is quite tolerably quiet. We bought the 12,000 btu unit. Probably overkill for a 180 sf bedroom. Will be bringing this larger unit to our Florida place and getting another smaller one for this upstairs bedroom up north. Only rated it a 4 purely because we just got it and have no track record yet. But seems quality built, nice item.
