I had two multifunction phone line connected printers die about a year apart after close proximity thunder storms. On the 2nd occasion I saw the lightning through a window, close enough to make me jump, with the sound almost instantaneous. VERY impressive.The printer immediately started a death gurgle :-) - slowly rising tone from line monitor speaker. I do not know how far away the strike was physically - I wish that I'd gone looking to see. The input COULD have been via the power lines, but on both occasions only the phone line connected printer died. | |

It's not perfect and won't hold off a direct strike. But it is pretty good at reducing some of the risks. I still have mine here despite replacing copper with fiber years ago. | |
