@dang, agreed that the product cannot be discussed on technical merits as of now, but I suggest some of the ancillary topics (irrelevant of their technical implementation) such as neuron sourcing might be worth opening.
That is one of the reasons why the "buy" CTA dispatches to a contact form. They can and must vet potential customers.
If I were to create such a machine, I'd make the whole top part replaceable, with the bottom part electronic-only. When your neuron culture runs its course, you detach the top part and ship it back to the maker, and buy a new one, with a fresh culture, at a discount. They recycle the top parts by cleaning them and re-populating them with new neurons. The sourcing liability is on them, as is quality control.
