Has anybody every seen a reg fail where it didn’t supply air when there was still air in the tank? Maybe a first stage. They are of sound design otherwise you would be diving with a complete spare setup all the time and would have been taught to do so in class and this sport would not be what it is today. The cheaper regs may not preform as well at various depths and temps but it will supply you air.

TRUE,
They are designed to "FAIL OPEN". Or, to put it another way, they are "NORMALLY OPEN, or flowing" But I still would not dive without a working octo.
