I really like the features on this AC.  It cools well and is quiet.  The Wifi feature is a plus.  But the installation hardware and procedure could be a whole lot better.    The side panels that block the window opening require weatherstripping, screws and clips.  My other brand AC is press fit into place.  This GE also has many gaps that need filling and/or weather stripping, again, could be much better if it all fit to the rectangular edges of the opening.  The window sash and sill form good borders and the side panels should fill the rest of the gap.  Instead I have to rig many steps to seal the opening.  Could be much better!
