Great product so far, I am using this as a stop gap measure as the central air needs replacing. Easy to install using product on first floor to cool approximately 1000 square feet, which is more than recommended square footage and it is working well! 
Positives: easy installation for two people, moderate for one. Have a partner when installing.
Really like the web app for operation.
Works well in a situation it is not designed for!
Little annoyance’s/Improvement  suggestions:
Noisy “thunks” when in econo mode and condenser turns on.
Cannot easily tell what mode unit is in when running for a while.
Not sure of reliability as unit has been in place for less than two months.

Hope this helps!
