I start by saying that I work as an assistant refrigeration technician. I have 1 in my studio apartment, 2 in our shop, and 2 9,000 BTU units in my parents' house. They are quiet (if you put the air on full, you can hear it a little bit more, but within a reasonable range). Excellent performance, the studio apartment drops from 29 to 27 degrees in 20 minutes. Daily consumption (for the 12,000 BTU unit) is 12 kWh even if it runs all day and night. Personally, I run it at 28 degrees on eco mode at night and from 27 to 29 degrees during the day, depending on the outside temperature (below 26 degrees it starts to get quite cold in the room). Due to my work, I can say that the build quality is quite good for the money, definitely an 8/10 for quality. We have not received any complaints or issues from customers so far (last 2 years). Overall, it is value for money in one phrase.
