Looking at MPs picture of Maria with a somewhat astounded look on her face while using an Evoliscope:

Is the image being relayed to the customers own personal hand held device where presumably it can be saved for future comparison against a more recent reading? There would be an app involved?

If so this must be topline customer service.

The ramifications are enormous.
Proof of the product working being displayed should generate a lot of loyal customers who will reorder and get further improvement and be kept in the loop.
Proof can be shared readily to friends and family via the customers' own social media links.
Add all this in to YPB and their tracer technology for China and they will be getting a service of outstanding quality assuming they go there with the Evoliscope technology.
