I love everything about this mod. I view a lot of mod reviews on Youtube and I'm honestly not tempted by any of them over my Archon. There is, however one feature I wish it had. A puff-counter that holds it's memory between battery changes would be very useful for people who want to use puff count as a measure of battery and coil life. If this could be added by a firmware upgrade, I'd add it immediately. Or this could be a feature on a future mod you manufacture.
