Hi all. I believe most of u hve heard of this electro therapy by dr. Cosmo? If not. Its actually some machine that produces enough electrons tht they claim will help to clean ur blood and promote overall wellness. Outside of that. I would like to check anyone here is able to tell me tht this product is safe to use for long term? Short term wise i can see a lot of people are benefiting for it. But long term wise... would it caise cancer ? Or any worst sickness? Plz advise... thx!
