I purchased this 10K BTU AC about 2 months ago and could not be happier. I have central air but the room I put this in has no vents from the central because of some remodeling Cat 5 hurricane Michael did. I had a smaller unit in the room but just was not doing the job. I love the energy saver feature as I set it to 74 at night and it shuts off most of the night. It has been a real blessing as Florida has been hotter than it usually is in June and July. Seems like the heat index has not dropped below 100 degrees since May. Its quite quite even on medium fan. I couldn't get the wifi to work but I probably would not use it anyway. I might try to get it to work with Alexa. I whole heartedly recommend this unit.
