I'll keep this brief: 
- The AC itself is genuinely beautiful -- neat and clean and (downside) it makes you realize how unattractive other air conditioners are.
- Installation guide is comprehensive and easy to follow -- and installation itself isn't that hard. (Just make sure you have all the tools lined up.)
- The AC is, indeed, very quiet -- a pleasant Shhhhh. Much quieter than my old one, though right now there's a slight rattle because my window's a bit loose and I haven't figured out how to tighten it all down. Yet.
- The air flow, diagonally out the top, not from the front, just works better.
- I don't love the "add AC to your WiFi/download app/sign up/etc.," but I understand most folks will see that as a good thing. For me, just a lot of steps for...?
