We absolutely love the way the knobs look and perform. We were changing out old knobs from the 90s and these make a huge difference. The only sticky wicket is that you may need to also purchase a mortise tool to help you chisel out your door so the hardware fits correctly. The tool is pretty inexpensive (about half the cost of one knob) and worth every penny as it makes the install quick and painless. We've purchased a dozen of these knobs as well as the privacy knobs and are very satisfied.
