I have seen a thief, two actually, with tools trying to saw their way through a ring lock. I don't know if they succeeded or not.
The ring lock gets used simply because the key is in the lock when you bike. When you park the bike, you remove the key which locks the bike. If you don't remove the key anyone can walk away, sorry, anyone can bike away using your bike. You just get in the habit of always removing the key.
Some folks have their house and work keys on the same key ring as their ring lock.
