Midea or clones there of. The model with the big giant oval hose is really a 2 hose model. If you have electric heat that you pay for, get the heat pump model instead. It absolutely cranks out the warm down to -5C. Then rely on your electric heat for the coldest days.
The first rule of portable air conditioners is get a 2 hose model (or the Midea with the giant oval hose that is really 2 hoses. 1 hose hose models are an america only thing. They blow out the very air you are trying to cool. The only reason they exist is 'stupid people are confused by 2 hoses'. 2 hoses balance the pressure and use outside air to cool the condenser. They are the correct choice.
I had the exact one for a year and returned it. It never really worked properly. Maybe I got a lemon but I exchanged it to the Midea 14000 BTU and no complaints
I also have horizontal windows! I have the Midea Duo and I love it. Super quiet and efficient. The remote acts as a thermostat too. It does need line of sight and it’s a bit finicky but that’s my only complaint.
i got this like last week! working great!
I use a Midea MAP14S1TBL to cool an entire 600 square foot apartment, and it does it admirably, and quietly. High fan speed is the loudest noise it makes. On my third summer with it, I've never had to drain it.

Very small footprint (13”x13”). It’s only 8000BTU, but that works well for me. I have a 12000BTU Midea heat pump that does the bulk of my heating and cooling and I just use the Hisense as surge capacity for afternoon solar gain when the sun is streaming in to my west facing condo windows. The Hisense has a reasonably good community integration into Home Assistant. My only complaint is that you can’t silence the beep when the unit switches on / off either from an internal signal, the remote, or Home Assistant automation. For this reason I used Home Assistant’s sun above / below horizon state to disable the Hisense at night. I’d rather deal with it being a bit warmer than the Hisense beeping as it cycles on/off. (See next post).

It’s been not that hot recently, so the Hisense hasn’t triggered and the Midea has done the base load cooling. But on sunny afternoons having an extra 8000BTU of cooling is very much needed.
