Excellent product! It's a 2-person job to install but worth the effort. The room cooled down quickly. It comes with the insulation too so we didn't have to stuff the windows with anything else. Hardest part was adjusting the screws for the outside of the unit to secure it in place. Once installed, no openings for little critters to get in.

My air conditioner arrived with a remote control and some foam blocks and adhesive sealer I could cut to size for installation and a remote along with two AAA batteries of the brand Blitz. I had to remove the two support knobs from the air conditioner as otherwise it wouldn't fit. My home has concrete walls and the interior and exterior window sill have a combined length of about 11 1/2 inches. The exterior sill protrudes the wall by about an inch I was able to slide it over the window sill by gently pushing down the unit. I guess I was right at the limit. 1/8 of an inch thicker and I wouldn't be able to use the U-shaped air conditioner. I checked with a bubble meter that it's slightly inclined to the outside to keep rain from flowing inside. In the manual, on page 9, under window requirements is a table that says the maximum window sill fit is 11 inches. But I could increase the maximum to 11 1/2 inches by removing the support knobs. 11 1/2 inches is the absolute maximum window sill fit in my experience. That was the only difficulty I had during installation. My old window AC covered a large portion of my window. The new one lets me see almost the entire window. The window AC's power cord has a fused and grounded 3-prong outlet and the manual says to plug it in to a 115 volts and 15 amps outlet. The first thing I noticed when I powered it on, it's not very loud and doesn't make a lot of mechanical noises or motor humming. The AC has a control panel right at the front top and I have to bend down a bit to reach the buttons.The control panel has buttons with lights to indicate what I selected. I have a power button to turn on and off the unit but to disconnect it from power, I have to unplug it. There’s a filter reset button that lights up every 250 hours, reminding me to clean the filter. I have a timer function, which lets me program the air conditioner to turn off or on anywhere from one to twenty-four hours in advance. Setting the timer is simple: I press the timer button and use the up or down arrows to select how long I want the AC to run or stay off. If I change my mind, I can cancel the timer during the flashing period by pressing the timer button again.I can adjust the temperature anywhere between 62 and 86 degrees Fahrenheit when in cool or energy saver mode. I learned from the manual that when I press and hold both arrow buttons at once for a few seconds switches the display between Celsius and Fahrenheit. The fan speed button lets me choose between high, low, and quiet operation, though I can’t change the speed in dry or sleep mode. The mode button cycles through cooling, dehumidifying, fan, auto, sleep, and energy saver settings. I like that in auto mode, the AC decides whether to cool or just circulate air based on the room temperature, and energy saver mode cycles the fan and compressor as needed to save electricity.The digital display is clear, showing the set temperature or the remaining hours on a timer, depending on what I’m adjusting. When I use fan mode, it even shows the current room temperature instead. The remote control mirrors most of the functions on the panel, so I can adjust everything from across the room. I can switch between modes, adjust the temperature, set the fan speed, and even activate a “My Temp” feature, which uses the remote’s location to determine where to cool. That’s especially useful if I want the AC to focus on the part of the room where I’m sitting. The remote also has dedicated buttons for energy saver, auto, and sleep modes, as well as a lock function to prevent accidental changes. Setting the timer with the remote is just as easy as on the main unit, letting me program auto-on or auto-off up to 24 hours in advance.And I can feel it's indeed a 12,000 BTU unit. The cold air fills the room quicker even with low fan speed than my old 10,000 BTU air conditioner. It has two vents where I can change horizontal and vertical direction of the cold air.

Easy to install. Excellent ac power!

We were a bit leery about purchasing this air conditioner due to there not being a lot of reviews yet and all the reviews seemed to from people who received this item free. Overall, I am so happy we purchased it! It's quiet and cooled the room right down. Installation was easy but took two people. We had to add some boards between the house and the screws to hold it in place because they weren't long enough but it's no big deal. The only thing I don't like is the water plug is on the part inside the house. Haven't used it very long yet but so far it seems worth the money and I absolutely love that we can still see out our window.

We just installed it. Easy to install, makes little noise, doesn't take up space in the window. Perfect! I'm going to buy it for my bedroom too.

My friend has one and when I go into house it's slways cool . Great quality, she said it was easy to install, noise level was only loud when fan was on high , looks fancy , she says it doesn't run her electric bill up . very functional

For starters, this thing is well made. Secondly, it's very quiet. About as quiet as what you'd expect from an in wall AC unit at a nice hotel (Marriott/Hyatt/Hilton) and MUCH quieter than ones you might find in an older best western, for example. Installation took about 15 minutes, 5 of which was wrestling it out of the box. As long as you can maneuver 50lbs with relative ease, the worst part of installing this for me was carrying it upstairs. Use the included foam to build a seal around it, set it in the window, and extend the legs on the outside to the right length to make it sit level....and that's it! This thing seriously could not be any easier to use, and the top of the U bracket is honestly WAY sturdier than one of these from Hisense I tried last year and returned from it having crumpled in on itself. I don't see that being an issue with this one *at all.It's hit 80 degrees here once, and having this upstairs for some extra cooling capacity has been WONDERFUL. Just as a test, I shut off the vent in my office, ran this, and it took all of 5 minutes to go from hot and icky to cool and temperate. That's in a 140 sqft room. This thing should be able to handle up to about 500sqft, so even if you didn't have central AC, an average 2000sqft home could easily be taken care of with just 3 or 4 of these. In my case, it's the perfect addon to let my built in AC work a little less hard and get a better balance of cool air upstairs. And the foam for the windows is very thick and dense, so I don't even see myself needing to take this out in winter. Heck, I might even put some plants on the shelf this creates right outside the window for the heck of it!It's also rained once so far, with moderate intensity (the kind you'd be okay driving in, but would have the windshield wipers on full blast for) and I didn't have ANY water get inside from my install. Window was wet. Outside of AC was clearly wet. But the foam was dry and nothing got past the outside of everything. Again, super impressed with how easy this was to install and how good the insulation is. And just look at that! My window is only 4 inches off the sill, and that's with having used some of the foam to make an additional foam seal in the bottom track.All in all, I'm simply amazed at this little thing, both in quality, quietness, ease of installation, and how powerful it is and quickly it cools. It might not have all the bells and whistles of one that's wifi controlled but I don't want that anyway. If you DO want to be able to control it remotely though, you can easily get a wifi IR controller like the ones linklink makes for 20 bucks, make it learn the remote buttons this comes with, and then control it from *that* app through your phone or home assistant like Alexa from anywhere.Also, if you've got this far, here's one final install tip: Instead of pulling it up and out of the box, just tear the sides off the box. Makes lifting it out so much simpler.
