Our first Window A/C. Love GE products that are mfg with inverter  technology with Eco mode. The installation was straight forward however we have Anderson Windows which we had to add a length of wood for the sill for A/C support. Beyond that, it connected to WiFi easly. Its been 1.5 hrs since initiating power. Would recommed this product for any large room under 550 sq ft.  Thank You GE for an exceptional design.
