Is Quantum Biofeedback safe?

Quantum biofeedback is a safe and non-invasive training with no side effects. The QUEX ED is a self-monitoring and self-adjusting device, taking its cues from the body’s electrical signals as training proceeds. The frequency used is so low that most people don’t even feel it. if they do, they describe the sensation as warm and pleasant. Alarms are also activated when the client has had enough of any one training, alerting the practitioner to switch to a different training or stop for the day. However, it is recommended to steer away from quantum biofeedback if you carry a pacemaker.
