Wow! Soooo quiet!! Cools very well and is efficient as well! Try this one for sure , it changed the game for our upstairs bedroom and is so quiet!  The eco mode is a little tricky, but we are working on it, Customer support has only told us to cut it off and turn it on again, and that really didnt do anything but we want to figure it out so maybe it might help anyone else who might encounter the same at first.
We have only had this for a few weeks, but it is a gamechanger as far as cooling and quietness!
