The AirCon is great.  One of the quieter units on the market.  It looks, runs, and cools great.  The WiFi light works double duty and it would be nice to have a dedicated power light. 
The app needs a lot of work.  When it works, it is excellent. Any changes (add a unit, app update, name change, etc.) messes it up requiring you to delete and reload the app.  The instructions for adding a second unit are non-existent.  Even with this hassle, it is a great unit and I would recommend it.  If the app developers and tech writers can get their act together, this would be a really fantastic unit.
