Everything falls into the same category: FDA
Do not expect much until such time.
The idea of Portable John's is something I have never considered. But do you really think someone will pay such prices? Ask yourself, has there ever been any complaints or lawsuits regarding transmission of disease due to portable John's? Then ask, what you would do if it were your company? Why not replace the really bad John's with a new one? Surely this company has the ability to either clean them regularly, or melt them down and build a new one. Also ask, how much it might cost as a service contract to decontaminate those portable John's?
We might have a few sales in Europe, but for this company to succeed right now, the big hurdle is FDA approval.
