These knobs are stunning.  I never imagined that door knobs could be such a statement piece but, these have lead the way for many design choices that we have made since purchasing.  I bought a wide variety of these in the same style (all matte black) and every one of them has exceeded my expectations.  We have had these (and the rest of its family) installed in our entire home for 2+ years now and I don't have a single complaint.  They were very easy to install and have held up remarkably, even the exterior ones.  I was very worried that they would chip or fade and that hasn't happened.  I have 2 small kids and these knobs look as new as the day I bought them.  These are one of my very favorite purchases, for multiple reasons!!
