About ten years ago, I put a $175.00 surge protector between my electric meter and the house. It has a little red light. If I get a surge it is supposed to blow the surge protector. If I see the little red light has gone off, the surge protector is shot, I was protected. Protection guaranteed up to $25,000 replacement of anything damaged. Is the guarantee any good?
Who knows, 10 years, and the little red light is still on.

P.S. the surge protector was sold by my local electric supplier.
