Sorry for all the questions tonight people. I am not a spammer. 
I just saw an ad for a BogeTech cartomizer tank and wondered how they (or any) tank works. The parts list shows the center pipe, the end to vape on, and two rings to connect the tank.
But what I didn't see was replacement cartomizers. Is there any? Or do you essentially use them like clearomizers?
Thanks.
Doug
