The case was widely reported by the media. More unhappy customers emerged, along with legal claims and counterclaims from Harness, who threatened legal action at every turn. A parade of electrical experts gave evidence on both sides, including the eminent physicist William Thomson, Lord Kelvin, who reported that the current produced by the Electropathic Belt was infinitesimal, if it existed at all. Others came forward and revealed that demonstrations at the Electropathic and Zander Institute, which showed that the current generated from the belt could ring a bell or light a bulb were staged. A concealed battery was used in the demonstrations, but there was no battery in the belts sold to customers.
