Very quiet and relatively easy to install. Probably easier with two people. Very quiet. Consider 3 stars because WiFi is a pain to set up; I still haven’t been able to. But it has a remote and buttons so not being able to connect to WiFi isn’t all that bad. Not what I paid for though.  Wife doesn’t like that it sticks out into the room as far as it does. Including the window sill ledge; about 8 inches.
Quiet, cools quickly, has button, has remotes, not to hard to install, WiFi is a pain, sticks out into the room a bit much. Pluses out the negatives
