Do you use a vape with a puff counter?

I'm curious how many of you use vapes with built-in puff counters that track usage.

For anyone that uses a vape with puff tracking, do you know how many puffs a day you take?

Never used puff counters even when my batteries had them. My vaping would vary so much depending on stress factors that it wouldn't be of any use to me. Some days I would chain vape while other days I might go hours without taking a hit. I know some people like to keep track so it's useful for them. Do you use it?
