trying human circuit

poirot84  asked:

How do they "Trying Human" circuit work to perfection? Do they experiment it before they gave them out to the Reptoids? Have they ever had any flaws in them like they stopped working without warning?

I’m sure the Reptoid scientists at Dulce experimented with them.  Reptoids can already shapeshift so it wasn’t as hard for them to make such a device as it would be for us.

The only way they can stop working is when the user is injured (see Chapter 17 Page 601) or with the use of a circuit jammer (see Chapter 12 Pages 378 + 379).
