The problem with stiction is that it could give you a different answer each time you nudge the instrument. Personally, I'd want pencil marks that have been checked carefully before starting work, and that won't move. Even a wrong reference is better than a wrong one which moves whilst you're in the middle of the job, particularly if it leaves no trace of where it was previously.
I've never used one, but I'm struggling to think of any job I've done where it would have been more convenient.
I doubted the concept for those very reasons, but after buying one, it seems to work perfectly. Presumably they'd be stuffed if you drop it once to often, but that's true of a level as well
