I purchased two of these air conditioners because they were said to be very quiet, and that is absolutely true.  They cool very well.  They are so quiet that I am not sure when they are on.  The only problem I have with them is that the display turns off after a while so I don't know what temperature the unit is set at unless I look at the remote control.  I can't tell what features have been activated unless I try to change one.  The unit as WiFi, but I haven't figured out how to use it.  The instructions are not very clear, and for GE, I found that very surprising and a bit disappointing.
