These are beautiful!  The only issue I have is the decorative  back plate is rather large so it extends about 1/8" - 1/4" over the "routered trim" of my cabinets.  It is not a bad look at all, but I would have preferred the plate to be a wee bit smaller.  The knobs themselves look very elegant.  They are a nice update to the polished brass knobs we had from about 20 years ago.
