Bought this as a replacement for a window unit cooling source that is getting old and we were thinking might give out at some time. 
This unit outperforms the window unit by a huge margin. 
Very easy to setup and get running. 
Love the “follow me” feature. 
I have never needed to drain it. 
Very quiet. Much quieter than a window unit. 
I will be purchasing another unit for another section of our home.
