What exactly did the physician test the qlink for on his "quantum physics machine"? For EMF protection? Better concentration? Lower blood pressure? Lower stress levels? And on what basis did he pronounce is valueless?
I have worn a Qlink for years and it has very definite effects some of them measurable (like the 10 points it lops off my blood pressure readings), and some that you can't measure like increased energy, calmness, etc.
