If you are a light sleeper, this is very hard to deal with. I like it for white noise, but it goes from full sound, to no sound, all night long
*does not have an inverter inside so it always runs at full power which isn't super efficient. It's also always loud.
*It's louder then I'd like it to be. It's hard to talk on phone next to it for example. And it's always that loud. You can change the fan speed but that barely changes sound level as compressor runs at full power. This got annoying as it's not pleasant to talk/listen to music/watch tv with it.
*because it's always running you'll want to manually turn it off and on. The remote control isn't bad and works fairly reliably if you point it directly at the unit. Otherwise it does not work. You can't reflect the signal at all. This got a bit annoying as well.
*internet control worked fairly well for a while. It was nice to be able to remotely turn it on before coming home. However recently it broke and refuses to connect at all.
*hot hose gets hot and this means that when you turn off the unit the room absorbs the hot tube and reheats fairly fast.
*I've gotten a hose insulator ($50), and that improved efficiency and how long my room stays cool.
*overall this unit would be good if you use it infrequently and somewhere far away from where you are. Do not buy for where you sleep or work. Otherwise buy one with an inverter.
Installation:
Hose is too short and I had to stretch mine. This unit has to sit directly under the bracket otherwise it won't reach.
Bracket is decent, seems like it would fit a lot of windows. It's nice that they have insulation material but it doesn't stay in well and you need tape to close up the holes anyway.

1 ton = 12,000 BTU = 3.517kW
The yellow EnergyGuide label reads: $108 per year @$0.13/kWh, 8 hours/day for 3 months.
Some thoughts:
- I've owned a 12,000 BTU portable AC before and it was much louder. This is actually fairly quiet and it sounds more like a white noise generator than a buzzing compressor. The noise is equivalent to my old AC's fan only mode.
- It's 8000 BTU rated so expect about ~800W per hour (edit: next poster says it's more like 1000W without spiking).
- On very hot days like 100F, I only made it to 85F for a 500 sq ft area.
- It's Hisense China, don't put it on your home network no matter if it works with Google and it says Wifi.
- Hose is pretty chunky, it's a good thing because these are the first things to rip apart after a while.
- I wish I can adjust the auto-opening flap without the remote.
- It has two hoses, one for outside air to cool down the compressor, the other to exhaust the compressor's heat. It keeps your area neutrally pressurized. There's another intake on the back, that recirculates the cold air.
- It also functions as a heater. It's more efficient to use this heat pump to heat your home than to use a purely resistive electrical heater like a heat dish or an oil-filled radiator. You're sending cold therms out and trading the outside air's heat indoors (kinda strange but it's true). Up to 50% more efficient than a resistive heater.
For winter, try to keep your roof crack free since hot air always wants to rise. When hot air escapes, It creates negative pressure for less dense cold air to seep in. Plug up vents. Make your home like a hot air balloon and let your ceilings contain it.
For the summer, to keep cold air in, Imagine those open air refrigeration units in the supermarket that don't have doors. They keep the cold air inside by sealing the bottom for cold. Cold air stays put and controlling it is like a cup of water.

One more fun fact - the dual hose a/c units also do a great job dispelling condensation through the exhaust blown out. Single hose units collect tons of condensation into a removeable bin, not unlike dehumifiers. This bin needs to be emptied frquently, othewise it would get full and hit a safetly sensor that turns the unit off.
I have last year's gray colored model (from Costco) and never had to use its drain plug to empty any internal condensation buildup.

-The noise level isn't bad at all on low and I'm able to sleep with it on.
-It has a nice "dimmer" function which turns off all the LEDs so your room isn't lit while you sleep.
-One big issue is the WiFi connectivity option which absolutely sucks nuts. Don't even bother trying it. The app sucks and it refuses to connect for me regardless of what I try. Others may have better luck.
-I also wish the hoses were a bit longer, but it's still perfectly fine for most applications. The heat hose does actually cool down after running it for a few hours so there's less heat radiating from it into the room. I wrapped all my hoses in aluminum foil to provide mediocre insulation/reflection of heat lol
For $300 on sale, this was an insta-buy for me. If you keep your AC on all the time at a constant temp, the 12,000 BTU Midea inverter unit deal at Costco for $450 might be more energy-efficient for you. Also, inverter units are quieter as it slows down the compressor instead of fully turning it on/off when it reaches temp like with non-inverter units.

One 12k BTU unit could require 1300W, another might require 1800W. There could be be a 14k BTU unit that draws 1300W. This is especially true for units like this one that don't have a continuously variable inverter, because it means they're drawing close to max power when they cycle on. That's where efficiency comes into play. The more efficient a unit is, the more it can cool with less power.
At 7.2 CEER, drawing 1000-1300kW for 8000 BTU, this unit is rather horribly inefficient even though it's more efficient than most single hose portables. Midea's DUO has a CEER of 12.3, has a cooling capacity of 12k BTU, and draws 1300kW max. It has a variable inverter though, so it will often draw much less than that.
