Why can I only feel Zeus on one side?

This is normal.
Zeus only needs contact on one side to function. This means the circuit is complete and the correct muscle is being stimulated.

If the stimulation feels uneven, gently press Zeus against your neck or slightly adjust its position. Small differences in skin texture or muscle thickness can change how the sensation feels — this is completely normal.

To test your device:

1. 1. Lightly touch one electrode with a wet finger — you should feel nothing.

   2. Then touch both electrodes at the same time — you should feel a light current, confirming the device is working correctly.
