Thank you Bob. I do appreciate your perserverance in a health industry filled with charlatans in my opinion. In my former career i demonstrated & sold & repaired welding apparatus of many types from square wave power supplies to plasma cutting technologies and was well trained in metalurgical technology. So i can appreciate integrity in business & can sense a scam when i catch wind of one. Healthy lives have always depended on trust of using devices of safe design & operation. I’ve been retired for sixteen years and as a older couple, my wife & i depend on pain relief & the potential healing effects of your devices. We also sent your A9 to our 92 year old aunt for scoliosis(it also helps her sleep better because of pain relief). Thank for you career choice to help folks!
