I bought this just before the 1st heat wave hit.  I'm on oxygen so having a quality A/C is critical to my health.  It worked great!  It was quiet, cooled of all the rooms I was hoping it would.  Very easy to use and I like the current inside temp feature on the remote.  I also like that I can use an app to control settings so I don't have to get up, find the remote and update the setting.
