I wondered what your experience of them was. The company I'm talking
about is

I bought one of their Mercury cables in 2005 and put it in a cupboard
shortly after as it did not do anything. While surfing around I came
across them again and their description of the cable is:
Not plated, layered, or bonded, here is a solid multicored silver power
cable we named "MERCURY".
I cut the cable up last night only to find it is nothing more than two
lengths of copper core coax where one core is live and the other
neutral. The earth is the copper shealths of each cable wound
together.
Solid silver, my a*se.
