Since you are Jack (John) Ellis' daughter maybe you can explain the logic behind your father's thinking regarding his machines. If they really do everything that he claims why would he NOT guarantee them 110% ???
If they truly cure everything from baldness to cancer and lupus to dirty water wouldn't he stand behind them?
I know that if I had a family member dying and your father's machine cured them I would should it from the mountains. I think this is the bottom line that most people cannot get past.
