It cools well. Heat, not so much. Running it heat mode it will freeze itself hard. In Auto it will struggle mightily but not freeze up.
Controls are ludicrous stupid. You can’t set the temp in auto mode, you have to set the temp for heat, and then cool, and then choose auto.
It has a 5” outlet with a lip of about 1/4” to attach duct to. Good luck finding 5” duct in the U.S. I have to duct tape the crap out of mine a couple of times a year.
The set temp varies wildly from the actual temp and every so often it just looses its mind. You go to sleep at 70 and wake up 3 hours later at 85.
The
price is good, and it’s quiet… YMMV
