I have this unit.

Install was pretty straight forward and easy. The "window stand" is pretty silly and huge for what it needs.
it blows cold and works well, but it is VERY noisy… and not just a hum, a whole variety on buzzes, bangs, and rattles.

These are awkward and heavy, to wrestle into a window and way too many screws to install to the window. This one is 12 lbs heavier than the Midea, but my Midea never reaches that 12k btu that it is supposed to. In fact, it seldom reaches more than half that. It rarely pulls more than 700 watts, even at aggressive settings with temp set to 60F, sensor detached and Flashcool on with Eco off. They have tuned it to make it spec as more economical by overrating its output, IMHO. It takes me hours to cool a 13 x 19 room.

I got the Hisense 8K unit from Costco.com in June and also found it too small for our living room. I had already destroyed the box but took it back to my local Costco yesterday for a refund and then purchased the Midea 12K unit at the store. No problem.

How's Costco with return. Got the 8unit for living room a month ago and it's not enough power. Takes too long to cool down.To return it do I need to package it how it was ? Hard to put it back together
Costco likely has the world's BEST AND EASIEST return policy so long as you either have a receipt or the membership no. it was purchased with. I'm a Cali girl and have been a member/have family with memberships since its inception in San Diego and while I am not a fan of this portion/though it can come in handy if truly applicable, I have witnessed ludacrous grossly used items people returned yrs later and still received full refund!! Not at all suggesting abuse, but this is a place you can buy with confidence! 🫶

Yikes. The Mideas have their quirks too (mine can sometimes tend to shake the window/wall a bit as it's spooling up from a dead stop), but mine at least is generally quiet/tolerable during normal operation. VERY quiet when it's not having to cool much and throttles itself down to ~100W. Guess this answers the question I had of whether I should use the recall refund to switch to this unit instead.
Sometimes you can wedge something bouncy or use a Bungie to the wall to create a secondary dampening element that stops the midea ramp-up take off sounds.

-(perfectly happy now midea owner)

That's why if I need any kind of a major purchase and if Costco carries it, I buy it there.

I bought the 8000 btu version and then returned it. There was a knocking noise of the fan hitting and damaging the refrigerant line. Sooner or later that line will break and leak all refrigerant out. I dont understand how hisense did not do any quality control.

So the "Ultra-Quiet Cooling—Peaceful Comfort" verbiage is a bit overaggressive?

I have one for the master bedroom that actually gets too much air flow. It's either an ice box or a sauna, depending on the season. I keep it on "Dry" mode and it seems to do the job. However, my bedroom is not that big, maybe 350 sq ft., max. My biggest irritation is that the remote's screen is not backlit, and it's quite hard to see, unless a light is shining directly on it.
Install was easy. Included insulation materials were adequate. You could make it better, but no real reason to take a trip to a home center.

As parents facing a possible empty nest in a few years, I could see myself purchasing more for other rooms and giving the central AC a break.

My unit is pretty silent. Others may not be. That probably speaks to a QC issue. You could get a good one, or a bad one. But the good thing is, it's from Costco. You can return and try again.

The unit is not very heavy. The weight is distributed somewhat awkwardly, but I didn't have any issues lifting it over and over again to check for fit and add more insulation strips, and such.

Thought about this but decided on the Midea unit for $9 more at my warehouse was better for us. It is the updated unit and will replace my recalled one, which works very well.
Is the 12,000 BTU Midea priced at $279 at the store as it is showing $309 online?

I also have it and mine is loud, but the word I would use to describe it is bass-y. It sounds like a subwoofer. I don't know how or why. It's doing a good job cooling the room it's in though

Does this happen to be related to the Midea U? They look like siblings

You could probably reduce that a lot by adding some padding under it. It's turning your wall/strcture into a sub. I have one that does that too. But it's not bad.

My unit like this one though is whisper quiet.
