I second this question. For those of us who don't work in this field and are looking to see if it's a device that offers any benefit. I mean at this point I'm not even asking to see a video of frequencies killing pathogens cuz I know it's never going to happen I'd settle for somebody proving to me it's something beyond just a box with lights. Just when I'm about to spend the cash I always wake up cynical wondering in this day of litigation and liability and restriction is anybody really producing a device that transmits a viable source of energy at a therapeutic level. Thank you for your input.
