quantum science- how does it work?

QUANTUM PENDANT is the most in demand product nowadays. my friends bought it for safety purposes.. others, for health protection.. but how does it really work? even i can't imagine how effective it was.. i tried it once. kasi i was so tired then and my friend offered her QUANTUM para suotin ko raw para mawala yung pagod.. hindi sya instant agad.. it will take few minutes bago tumalab.. hindi na nga ako inantok.. this product is made from Japan.. pati ako napaisip, paano kaya nangyari yun?.. is it a miracle? or siguro grabeh na talaga ang nagagawa ngayon ng science sa ating buhay...
