I have seen a HUGE difference in my life with the use of my anion emitter pen! ( no Advil in six weeks 4/6) I work out with Evette Motley Pack, and she wears her pen every day! I have talked with Patty Pollard Ralls and Ron, and Ron say’s it has been a life changer! I will supply some fact sheets in the comment area! You can look into the anion pen and cation shields from my website: https://rlpedone84.juuva.biz/
