Arrived on time with no damage, and works great, cools the room real nicely and the Sleep features have been handy. However, worth mentioning that I obtained this AC at a discount that rounded the final price to 618 approximately so my value for this may vary.

This unit was purchased to help cool off 300 sqft of upstairs of an almost century old home with poor central ac to the top unit. It is far exceeding that capability and effectively and easily cooling over 700 sq ft. Inverters are the way to go for quick efficent cooling!

This unit is quiet, energy efficient, and is a legit heat pump heater as well as an air conditioner. The only caveat is that it will not start heating if the outside temperature is less than 41 degrees Fahrenheit. This is perfect if you are in a southern state where temperatures do not approach freezing even during winter. Super-efficient as a heater during the winter.
