First, this was the easiest install of a portable AC. Everything was ready to go.  My window requires vertical installation of the window panel. This Haier adjustable window panel was the simplest to adjust vertically. Press two attached clips and the panel is perfect size. The notch in the back of the AC for the remote means we won't misplace it when not in use. And yes, the unit works perfectly.  Only one suggestion. Add a few more inches to the vent tube.  Just barely reaches the window panel vent opening while leaving the suggested air space between the unit and wall.
