I bought a few with a couple of drip tips a few months back, to be truthful I'm still on the first one had maybe 90ml of
juice through it. That one has a slightly tighter draw than my 306's, I don't know if that applies to them all or not yet. Flavour is great, vapour production is amazing, I think you're going to enjoy it.
Lol sorry if that's not much help.
Mark.
