Yeah, it's easy enough. I just got so used to not having to remove the tank (from my mod) to fill. So it's just an extra step. But I'm so glad you turned me on to this tank. Getting the airflow set perfect, and then never having to touch it again is just great. And I'm getting 4+ days out of the coil. So I have no complaints. So, what makes the real Kabuki any better?
