I was happy to purchase this product as it came recommended on the Wirecutter, and usually that website does not steer me wrong. But after fumbling for days with the installation, I must say: avoid this product. Other window units I have owned I just pop them in and they work. Once I had to install a thin wood board so that it was propped up. They all worked. 

But with this one, when installed tilted downward slightly, it vibrated against my window in such a way that you could hear it down the street. Impossible to live with that. So I propped it up to be level, which made the noise tolerable (though not great) but then the water began draining indoors instead. LG unhelpfully chalks these issues up to installation error. I chalk it up to product design. Never had an issue with window unit installations before.

The unit is also very bulky, making installation annoying. 

Get something else.
