We've had both the Midea and the HiSense ones. We loved the several Midea ones we had, but they got recalled for the mold issue after we'd used them for about 3 years. The recall $$ more than covered the HiSense replacement. So far, the HiSense has also been really great. It blows as cold as the Midea, and since both are inverter tech, both are really very quiet. I've got to assume Midea has figured out the challenges with mold now, so the biggest difference between the two is the design. For me, the HiSense has been a much improved overall experience.
I don't keep the AC in the bedroom window all year, so the process of install and pulling it is important. While both are somewhat heavy, the Midea one always felt like it would flex and collapse on itself when lifting it out of the window. The HiSense feels much more compact and rigid. I haven't checked, but it also seems smaller/lighter. My wife is really sensitive to light in the room when we sleep, and one challenge with the Midea one is that in order for the room blind to black out the room, it would have to slide behind the room side of the AC unit (in between the ac and the window). For the HiSense, this is not an issue since the blinds can come down to the top of the room side of the unit, and then the sides are blocked out with the included foam. We use a roller shade, so it was thin enough to fit between the AC and window on the Midea, but if we had other options like mini-blinds or slats, we would have had a lot of light in the room with the Midea.
Since we mostly keep the blinds down in our room, the other benefit of the HiSense is aesthetic - there is only a small footprint on the room side of the AC unit.
Again, this is not to say there is anything wrong with the Midea as long as they've fixed the mold. It was really great as well. In terms of function, they both seem to be pretty equal. The HiSense ones had several sales last year through Costco. As it is getting hotter, I wouldn't wait to get one, but if you get one Costco, be sure to watch out for a drop in price in the 30 days after since they will honor the price adjustment as long as you request during the time it is on sale and within 30 days of purchase.

I have two of these and I really like them. I would get a third one if it would fit in the window I need it to.

The Midea SmartHome app shows power consumption for the units and they are very efficient since they are inverter ACs.

Mine shows energy reporting not supported! Shows having latest firmware. Is any change new to turn on energy reporting?

At one point I had the energy monitor only showing on one of the two units, but the other one didn't say it wasn't supported, it just didn't show energy monitoring as a feature at all. Then one day it just showed up and worked, I hadn't performed any recent updates.

I did perform device firmware updates on both units during initial setup through the app, but it didn't coincide with the energy monitor suddenly working 🤷

I have a question for you guys. I live in an old apartment that runs all electricity on one circuit breaker. So I cannot have too many appliances run at once. Currently I have the 8000 BTU Midea U shape and another 8k btu Frigidaire that I need to replace. I wonder if I get the Midea 12000 btu would it draw too much electricity and causing the circuit to break or would it only draw enough to cool the same room where the 8000 is now? This place is so bad that I can't have a Toaster, Microwave and blow drier running at once. So I'm afraid to increase the BTU from the current 8000 to a 12000. Any enlightenment is appreciated.

Same mismatch on the portable model I want to get, hoping at least the local warehouse will have it at the advertised price.

I installed this just last weekend, and that was a refurb one from Walmart - $259.99. They had a prior issue with the drain plug that had to be replaced, so that's really the only refurb aspect - and the plugs have been changed to a different design.
The unit itself so far has been great. I got mine for my master bed/bathroom at nighttime so I don't have to run the whole house (downstairs as always is a lot cooler than upstairs). Tested a few times and it worked great for the space I have.
