4. Tell us what functions do you think a mod should have
Definitely good quality construction and good chips that don't poop out on ya in a month. A crisp, clear, large, easy to read screen (some of us have old eyes), and a user friendly menu. I like having batt level indicators, but really prefer it telling me in numbers how many volts are left on my batts
REVERSE POLARITY PROTECTION. I think it's absurd for a mod to not have this.
Floating 510 pin, same as above.
