What happened to purchasing and putting into window?? it was absolutely a ridiculous nightmare took over an hour to put into a second floor window.  We have a this same model only older x2 and you can just slide them into a window, not with this new model.  There isn't a long built in bracket anymore on the bottom, you have to separate the casing from the air-conditioner to put it into a window.  Terrible design, then the nuts for the brackets were too short, we had to buy extra nuts that were longer to fit the brackets that hold the air-conditioner in the window. LG needs to go back to the way they used to make them.  This years model is a terrible design.
