We had a five-bedroom, six-bath house with exactly those knobs. After seven years--including two with the subsequent owner--only a bit of shiny brass revealed on a couple of them. To keep the look consistent, I eventually interchanged them to balance the wear. I'd use them again in an instant. The only problem was with the privacy lockpins that tended to fall out; probably could be cured with a dab of thread locker.

Thank you! Your comment is so helpful. I like the idea of gold highlights, but didn't want shiny brass knobs within a year.

Thanks. I am also considering the medium bronze finish for cabinet pulls/ knobs since they also have cup pulls, multipoint sets, and interior hardware (French Antique Brass) that ties in nicely together at a more reasonable price point than luxury brands.
