Hobbs meters ever "go bad"?

Sure, it's a mechanical device.

On two occasions over the last few years, my Hobbs has failed to move.

For this reason, I always note my tach time and time off. The extra
start numbers will help just in case I don't notice for a while that the
Hobbs isn't running, and I need to have a fuel consumption figure.
