Replacement part for the Thoughtstream Biofeedback Device (not included)

Replacement palm sensor is the exact same sensor that comes with the Thoughtstream - in case you lose or damage the originals.

The replacement palm sensor includes ONLY the palm sensor and DOES NOT include the ThoughtStream biofeedback machine pictured here. The photos are for illustration purposes to show the palm sensor in use with the ThoughtStream Biofeedback machine (not included).
