Nice review. I agree with the others, the t-shirt was a bit, um, noticeable.
As far as the tank goes, I remember a
@pbusardo video of a vape show (Miami, I think) where he bumped into a guy who was making tanks with a similar type of airflow and I thought, "That sounds like it might be a good idea." I'm glad to see Innokin try it out.
RBA section is becoming a must, I think. Ever since another company included such a section with their tanks, it has become something that many people want--either as part of the kit or as an inexpensive add-on.
