They never run out of batteries.

They are willing to deploy a personal touch
They are willing to take great risks in order to get the job done
Unless you need a more vigorous wake-up-call, in which case they are happy to oblige.
They are both timely and persistent.
They will perform their role in a regular and timely fashion without getting too invested in it.
