Interferential Current (IFC) therapy is a non-invasive, electrical stimulation technique used to reduce pain, inflammation, and muscle spasms by delivering, high-frequency, electrical impulses through the skin to deeper tissues. It often involves using 4 pads to cross-currents for better pain management in injuries. It was around $300 new. It includes a fairly new rechargeable battery. It also comes with an extra set of wires and a set of 4 electrodes. Works great, but just not using it anymore. Asking $95 or any reasonable offer. Thanks
