If it never fails, then why would it ever need to be replaced?
Even you yourself explained how every surge degrades a surge protector.

Explained multiple times. You intentionally ignore it to argue. A degraded protector remains functional. So yes, it might degrade so much as to need replacement in 100 years. But so will the roof. Do you also replace your roof after every rain? It also degrades.

Catastrophic failure is unacceptable in a protector. But that was explained how many times over how many years? Could you just once stop ignoring facts? Then you would not post reams of attacks. The request is that you learn. But that is not why you are here - is it.
