This air-conditioner is now taking care of cooling off the entire apartment and the noise issue mentioned by some customers is not that bad at all. 
Installation of the plastic panel and two exhausting ducts was also a nice surprise: we really thought it would not fit our window. However, a better and thicker plastic would be nice as the thread the four screws make are not sturdy/firm enough. 
The large size of the box and its weight would have been an issue had the delivery truck man not brough it all the way to our door steps (a high-rise).
All in all, a pleasant experience.
