I bought the nickel rod. It was easy enough to cut and install if you have a second set of hands just to hold it steady. I scuffed it a little bit in the cut/install but that was on me. 

It's held up great for a year now without any rust or blemishes. It's sagging just a little bit at the corner, but not too bad. I would try to use a lighter weight shower curtain with this, but I'd buy it again.
