I purchased these for two big windows in my living room in the copper finish.  They were very easy to install and they look vey nice.  My only complaint is that they didn't come with a center support piece.  It seems necessary for a rod that extends that far.  Luckily, we are very easy on our curtains and they aren't particularly heavy so I haven't noticed a sagging in the center.  But I would highly recommend purchasing something with a center support instead if you have heavier curtains.
