“Solid mod. After experiencing some of the DNA80C chips out there, I'd have to say that the non-DNA80 variant is more consistent in terms of reliability vs. feature set, and it also shows you real time voltage as you're doing your puffs so you'll get an idea of how much wattage you're actually drawing from the battery (without connecting to a PC) vs just seeing "Weak Battery" or "Error" on the DNA Chip. That said, It's still a phenomenal mod and I'd highly recommend.”
