Air conditioner works well overall and does the job to cool a room, but set up was a pain, the hose doesn’t fit as it should, screws provided were too small, and the window seal leaves many gaps that need to be plugged up. I also needed to buy a vent cover as large bugs were coming through the hose. Not what I thought it would be, and not worth it. I wish I could have returned and just bought a normal window AC which works just as well with way less hassle but missed my return period. It is also not truly portable bc of the weight, and the window fitting. Would not recommend if you were like me, looking for a solution to cool multiple rooms with a portable AC as that is not what I am able to use it for. Go cheaper and buy a window unit.
