Gave these a 4 because I had to look up on line how to put them together - you would assume a 3 piece rod would be easy.  But... one of the rods that has the end finial is actually the center piece.  Then you have to use the Allen wrench to attach it to another rod as the end piece.  None of this was terribly difficult - just not what I was expecting and there were no instructions.  Once up the rod looks great.
