At least for $399 the iTorus 2: Sedona Vortex Stone Therapeutic Vortex PEMF Tesla Healing Generator has blinking lights. If I pay that kind of money, I want blinking lights. When I Google "electromagnetic emf 5G", the #1 hit gives me a $239.96 passive device: "Lifetune Room EMR Modulation Technology protects you from the harmful effects of electromagnetic radiation emitted by data-transmitting devices found in any home, office or vehicle." $239.96 and no blinking lights? I'll pay the extra $159.04 and at least get some blinking lights.
