The main issue that I have with them is that their temperature control/regulation is messed up and the company won't do anything about it in terms of warranty support. If I set one to heat mode and set the temperature setting to a given temp like 72 degrees, the heat starts blasting, and continues heating up until the room is well over 100; it NEVER stops when it's on heating mode-- whether it's set to a temperature the standard way, or with the "follow me" mode on the remote.
When it's in A/C mode or Auto (which uses either A/C or heat as needed) the temperature regulation is extremely poor, when set to 72, the room will vary between 60 and 80.
There are also various more minor issues: the manual contains multiple errors, such as the hole cutout template is wrong for this model etc etc, the wiring diagram was wrong in the manual, and the wiring terminal label sticker was missing from both of my outdoor condensor units. All of these things just point to poor english language technical support from the company.
They don't stand by offering any meaningful warranty support to licensed contractors, and they openly state that homeowners/handyman installers won't get warranty support at all.
After a couple phone calls or emails, they promise to have their tech guys get back in touch, but you never hear from them again.
In the interest of fairness, there are several pros for these models though:
-These units are pretty easy to install (other than relatively minor issues with the manual and wiring diagrams) Also if you're not experience with cutting and brazing the refrigerant lines, then you'll likely wind up with an unsightly coil of extra line somewhere.
-They are QUIET. I don't have a decibel meter, but they are drastically quieter than any window unit or household central A/C that I have heard
- They are quite efficient compared to central A/C units or window/portable units
I hoped that these units could be an economical alternative to higher end brands, but while their mechanical performance is apparently quite good; they are quiet, powerful, and efficient-- the numerous electronic issues make this models a poor choice IME

They're incredibly quiet on low setting, which is main reason for purchase, so am happy with them. 2 small nitpicks I have are (1) misc foam provided for insulation used for sides of A/C makes it look so cheap - I'll need to find something to cover both interior and exterior. (2) there's a VERY loud beep every time a button is pressed and discovered new models allow this beep to be turned off in the app but older models like mine (manuf 10/20) are stuck with it. Still am happy with purchase.

Minisplits are an amazing way to heat/cool older houses if you need to retrofit something. I just did it because is was so much cheaper than a central heat/air system ($2700 vs ~$15k)

But the window is still open a few inches and the compressor is right on the other side of the glass, so I'm curious as to how much quieter they are than a traditional window unit.
A mini split keeps the window closed and the compressor even further away and will give the occupant the quietest performance. And some mini splits, including this one, can heat via heat pump.
There are some "teardowns" on YouTube, seems like they went for higher quality components across the board and each bit contributes to lower noise. Whatever they did, I'm very very happy with the noise level.
It's still a fan, but on par with a coway mighty about halfway between their setting "2" and "3" (actually rather closer to the 2 but still also definitely rather louder) I only really hear the fan noise from the Midea and a quiet non-rhythmic ticking that I assume is the coolant or maybe the compressor.
The other benefit is that the Midea is 120V whereas almost all mini splits are 240V. That's not possible for me to wire up in a rental.

Good forward thinking of you though!
Great AC unit though. Have an 8K one myself.
