Quote from a dealer who is a Reiki master and asked us to get the bio light for her: “It (using the LED) triples or more the bio disc. You put the bio disc in it. It turns counterclockwise. It has given me super results!!! I like the results I am receiving! I am using it in a person who has sciatica and I just hear all the bones doing crack, crack, crack and the person saying ouch, ouch, ouch, like with a chiropractor. I am so amazed that I laugh when I hear all those sounds and he says that he feels much better. I laugh because I am amazed at the results. I also did it with a person with carpal tunnel, and I gave her just once with the bio disc and the led. The first day she felt better. The next day she felt some kind of energy in her thumbs. On the third day she was okay. I did her just once!!!!!” Note: The bio light does come with the silicone protector ring. You do not need to buy the bio disc and protective ring separately. This purchase comes with 2 rings.The funnel is not included and must be purchased separately. The funnel only shows how it looks attached to the torch.
