If you can deal with those first-world problems, highly recommended!
The downsides of the heat function are:
It only works if the temp outside is above 42 degrees. So depending on your climate this may only be useful for chilly spring and autumn days.
It generates a lot of condensate so you have to hook a hose up to the highest drain and empty the bucket every now and then.
When it's cold out, and the unit is not in use but still hooked up to the window, a lot of cold air is going to come in through the duct hose. This can also cause a lot of condensation to build up underneath the unit where the cold air pours out onto the floor. You really have to pull it out of the window and shut the window when it's not in use if it's cold outside.
Make sure you wrap the duct hose with the included sleeve if using heat mode, to prevent condensate from building on the duct hose.
Overall I would say it's good for chilly spring / autumn days where you need a little extra warmth but don't want to turn on the furnace, but not so useful for very cold days like in the dead of winter.

Also saw someone say they had to disconnect one of these in the winter due to cold air sitting in the hose and causing moisture issues?

Also any idea on the hose length and just how sturdy it is? I have an older LG single hose and the hose will crack with almost any bending, so it needs to be held in one single spot.
Last question -- my LG hose needed to be wrapped with lots of insulation around the hose (the metallic wrap and tape) to prevent the exhaust heat from warming the room, would that be of any benefit to this type of model, or just run it as-is?
I bought this Midea last year and have been loving it. Not too loud, even on high, but it doesn't often go to high regardless. I have it for cooling our downstairs, probably about 1000sqft and it does a damn good job. The variable fan speed is great, half the time its on, I don't even hear it. I think this is where the inverter technology really shines. I haven't had a breaker trip at all and the room this is in is also tied to half the circuits in the kitchen. I've ran the microwave, air fryer, and toaster while the AC was going (not all at once, just one at a time).
I don't use the remote, so can't speak on that--But all portable AC remotes seem cheap and janky, imo. Haven't used the wifi controls either, just because I have a distrust for apps from brands I never heard of.

If you put the unit in a small room with the door closed and put your hand near the space under/around the door, you can feel a definite inflow of air coming in when the unit is in operation versus turned off. It's nowhere near as much as single hose units I've tried, but it's there.
If you search the Amazon reviews for this unit for the term "negative pressure", you'll find other people mentioning the same thing.
My thought would be that since the air is being condition, therefore taking up less space, so that pulls in more unconditioned air. But maybe my understanding of thermodynamics and air pressure are flawed. I only know what the weather guy/gal on the news tries to convey to me.
Ecoflow has one thats for smallish areas
