I actually bought the JU 99 along with two medium Orgone pyramids and a pair of structurally linked Pendants. They arrived promptly and were wrapped securely. All good. I already had a nine dial radionics box (R Box) and was intrigued by the quality of the orgonite from orgonegenerator dot com. I understood the surface area point about the black iron powder from the explanations I had read about activated charcoal in water filters. I had been working on a physical thing with it but it seemed to be taking a long time. And honestly, I wasn't real confident it was doing anything. I know I wanted it to. But when I added these new elements to my R Box, the operation was done in a few days. There was clearly a change... for the better ! I'm not one who "feels" the energy from crystals and such, but when I turned on the JU 99, I definitely felt something. It was "weird". I don't know how to describe it. I don't know if I made it up cause I know we humans do that. But yeah, I felt something. I put the round link on the JU 99 and I keep the smaller one with me in a small drawstring pouch night and day. And I point the JU 99 at my R Box with the two pyramids on the input over the sigil and one sitting on the dials. And now that I have been working with it on a couple of things, I'm Very glad I have it all. In fact, I might add a couple more medium pyramids soon. I'm convinced these additions have bumped up the power of my old R box Significantly!
