Soothe what ails you! The Sacred Cubit Feedback Loop, 24K gold plated is similar to the Acu-Vac Coil in that it can be helpful with physical ailments. When describing the two, Slim fondly compared the Acu-Vac Coil to a water hose and the Feedback Loop to a power-washer for relieving the body of discomfort. They have a similar action.
Slim designed this tool with his friend Bill Reid who described it in the following way: The idea is to take the negative energy from an injured part of the body, mirror that energy, change the phase and feed it back into the body. The process is called a wave canceller.
