Don Croft and his daughter, Nora, at Mount Shasta. "The morning after my first zapping, I awoke with a feeling of euphoria, which I couldn't explain," said Croft. After a few moments, Croft remembered that Dr. Clark said there is a connection between depression and brain parasites. "I cured myself and 'got happy,' stated Croft, "I had to know if Dr. Clark's other claims were valid." To say that Croft was excited would be an understatement. He began asking friends and family to try his Zapper. His enthusiasm must have sold them as Croft was "astonished" by how readily most people agreed to try his Zapper. "A friend, guinea pig really, agreed to use the Zapper and quickly cured several acute health problems. Her visual transformation over the course of a week remains as the most remarkable event that I've witnessed." "My friend became as excited about the Zapper's possibilities as I was. I began making Zapper units to lend to her friends. In all, roughly thirty Zapper units were loaned out which accounted for cures of varied illnesses including cancer, lupus, migraines, herpes, depression, colitis, ulcers, and a plethora of other ailments that baffled their doctors." The thirty plus Zapper cures were validation enough for Croft.  He was quite sure Dr. Clark's claims were credible.  Croft has been confidently building Zapper units ever since.
