Congratulations, Nad. !
I'm thrilled to hear that Kevin managed to get the extra hour during testing for CE rating.
Much more appropriate for a CCR of this design, purpose and price.
The Ouroboros is one of the most impressive CCRs I've seen, and Kevin icorporated several features I like. Not just the off-board plug-ins that are mentioned, but also switches to isolate automatic gas addition (solenoid and ADV) from manual gas addition. Little things like that, and there are plenty of them.
I'm really looking forward for more feedback.
