Instructions aren’t incredibly clear. They do not show the foam pieces when you are trying to install the side panels. The foam prevents the panels from fully covering the sides. The bottom piece where you screw in the bottom portion of the panel into your window sill should also be much longer. Ours was incredibly close to the edge of the window and the screw almost didn’t make it in. The AC unit looks nice and modern, and having an app to control it is very convenient. I don’t think it is as silent as advertised. It kind of sounds like any other AC unit.
