I believe the G4 is not currently available and is, in fact, still under development, especially the multi-component analysis feature that CDEx has advertised since day one.
I believe we will see a downgraded version with many limitations if they are ever actually produced for hospital use.
Since CDEx has evidently ignored independent testing I believe there is much more development required before any product will be avaliable.
I further believe that CDEx continues to be the same SCAM as pennstreet has admitted to it always being.
