Got these to replace a similar antique door lock on a century home bathroom door. The turn mechanism is very stiff, added some silicone lubricant which helped a little. Also if you pull the knob hard enough you can pull the thumb turn right out of the lock after installation - which could cause someone to lock themselves in the bathroom. Not great.

Matched great and easy to install

a simple and handsome lock, we needed it for a half bathroom with antique hardware that doesn't lock. unfortunately the installer didn't quite line up the strike plate properly and some people manage to break the lock. i've had to remove it, reset it, and reinstall it twice after 2 family events - could be a little more durable.
