I purchased this AC 2 weeks ago and it works fine but the remote has the wrong backing which does not allow battery installation.  Vendor ordered new one with no estimated delivery time.  Local service person will not respond.  Directional adjustment has only minor affect as most of the cool air is directed straight ahead.  Also check the plug orientation with respect to your outlet.  This plug orientation with my 1990 outlet does not allow another 3 pronged plug to be inserted.
