I was so excited when this arrived.  Assembly was going well and I anticipated having it usable within the hour. Then I came to the extension poles WHICH ARE A MUST FOR MY WIDER DOORWAY.  Check out the photos here. Someone did not even fully insert the male threads on the end of the pipe.  It is now too long to use.  Horrible!  I shelled out so much money for THIS??  And I need it tomorrow!  I am so upset (can ya tell?)
