I am well pleased with this air conditioner.  Beginning with the fact that it was packaged well and thus in perfect condition and ending with the fact that it is exactly what I was looking for. First IT IS SIMPLE TO OPERATE control wise and you don't need an IT degree to figure out how to operate it! That's important to me. It installs easily. IMO it operates quietly. It cools very well and cycles perfectly to maintain whatever temperature I select. It has plenty of cooling power. It is exactly what I needed and wanted and I am very happy with it.
