The good: Extremely quiet except for occasional rumble. Very solid installation and seals window much better than traditional units with accordion flaps. Nice to be able to open window if needed.
"Dry" dehumidify mode works very well. Extremely efficient, power consumption is almost impossibly low. $43 per YEAR energy rating.
Not as good: Has heat mode on the remote, but no heat mode in the unit. It would be a total killer with heat pump for chilly days.
Installation is not as easy as it looks. In particular, aligning the support legs to get it level. The unit has to be in place to check the level because vinyl siding compresses once the weight is on it. The 3 top adjustment holes at the inside of the sill need to be slightly farther apart to provide better "between" settings for the legs. These screws were so tight, it took an impact driver to loosen them without damaging them. The dense foam blocks are difficult to cut straight without tools for doing so. Cutting by hand will make them crooked. An electric knife and bread slicing guide worked in a pinch.
The rails the unit sits on create two "bug tunnels" under the unit. Look under the front from the inside and you will see what I mean. Be sure and block them with foam. The bracket should really have foam between the parts from the factory.
The variable speed compressor occasionally hits a resonance with the wall and rumbles like a distant helicopter. It does cool well if you set it on Cool, Fan High and leave it alone.
After receiving the electric bill for June 20-July 20, the bill is down 350 kWh from the same period a year ago at one degree higher average temperature. Very impressive! At that rate it will pay for itself in two years.
Update: The app works pretty well and includes a very handy weekly time scheduler with plenty of change points. There are some oddities in it, for one example, you can set it to High Fan in the program, but that means 80% on the unit. You can't program Eco mode, either. It is nice to set Dry mode for a short period every day to reduce the indoor humidity without getting too cold.
Scheduling does not work unless the phone/tablet is on and the app running, at least in the background. It doesn't use much power in the background, fortunately.
Update 2: I bought another unit, this one 10,000 BTU. Its fan runs faster and makes more fan noise than the 8000.

FIVE STAR PART: The unit installs in classic vertical sash windows, but unlike conventional window units, it separates the compressor, motors, and fans from the controls by allowing the lower sash to divide these elements. Brilliant: efficient moving components outside and cool, dry air inside. The space for the lower sash is also wide enough to permit a window blind to function in the gap. This allows light blocking, which is not something one would have thought important, but is, and it is very slick. The marketing literature talks about being able to operate the lower slider if you want fresh air, which seems silly. There is already a fan setting to bring in fresh air, and it is a fair bit of effort to make sure everything reseals when moving the sash. I think the marketing team went a little too far in this one and the notion detracts attention from the overall design excellence of the product.
It is very thoughtful to include a remote control for those needing one, and the voice access through Wi-Fi provides even more accessibility options. I am fortunate enough to not need these, and the on-board control layout of the unit is excellent! Although it took me a while to get used to a display that only showed the temperature setting and not the room temperature, it turned out that the unit is so good that there is rarely a difference anyway.
THREE STAR PART: You may have a little effort on your part to get the mounting bracket to work, since it is designed for specific sill configurations. A few people must be lucky, and it all works out, but our outer sill was too big. So, when the unit is installed, we put a conveniently sized brick on top of the sill (shown in the picture) and don’t use the rear angled support arms. We also put a thin piece of rubber between the metal of the mounting bracket and brick to reduce possible vibration transmission. (My calculations show it's very safe since the majority of load goes through the wall of the house in compression. Plus, the additional load is quite small. But we leave critical decisions of this nature to lawyers; think of this a shared experience from a questionable source.) Once you get the unit positioning sorted out, the mounting bracket is a dream, and next year's install will be easy-peasy.
I strongly recommend this unit! The price and effort are well worth it but do your homework.
