Bought 4 of these after lightning killed many in my house. A direct hit to a buried cable in the yard disabled a cable modem, router, cable TV to IP converter, and several switches and other devices connected to that switch. I now use them as electrical isolation between my cable modem and router and my IPTV and local area network.
