That ECI stuff is more of a true contact enhancer, nano carbon particles designed to reduce the micro-arcing that occurs when the signal jumps across microscopically small gaps in between conductors. That is part of what TC does. They are similar in using some kind of oil based carrier. With TC the carrier evaporates leaving only the nano-particles behind. ECI uses an oil designed to stay oily a long time. Probably the biggest difference however is the way TC works not only on contact points but anywhere near a signal. You could paste that stuff on the inside of a AC outlet cover plate where nothing electrical touches and it would still produce about the same effect as if it was directly on the contact points. Crazy but true.
