Packing was good lots of foam padding. Owners manuel was right on top with double packaged screws. The side curtains and top bar have to be aligned and screwed onto the unit. Takes a bit of wiggle to start the screws. Lifted the unit into window and spread out side curtains. I screw the side curtains to my window frame to keep them tight, I added a small block of wood on the outside lower corner of side curtains to keep them tight aganst the lower window frame. Time to load battarys into remote and volia works great keeps our 16X16 bedroom cool and crisp. We are considering another one for my kids playroom.
