I liked that the product came with all the necessary materials to properly install. Installation wasn't difficult and directions were good. It was a little tricky for  me only because it barely fit my window and happened to be the only unit available that would fit my window that was 12000+ BTU. It works very well and I like that it provides multiple ways to operate it. I'll use the remote and my wife  uses the wifi connection. Unit maintenance seems pretty straightforward and easy to do.
