After a MAJOR annoyance inputting it together(!)* it went up with only a few words from my husband. 
*Beware -- the screws that go into the rods MAY be STUCK INSIDE the rod with no way in hell of getting them out.) After trying everything we could thing of to get the screw out of the rod, the spirits changed course and gave us a hand....OUT OF THE BLUE, THE SCREW JUST FELL OUT. Period. Fell out. And, the day was saved!!
NOW, we LOVE our Twilight Room Darkening Double Curtain Rods and are actually considering buying a couple more!!
The loss of the 5th star is due to the DAMNABLE problem we had getting that screw out!!
