Yeah I guess that only somewhat helps me. I don't yet understand the difference between an atty and a cartomizer. What I'm using now has an atomizer but I dont know the difference. It sounds like more work than it's worth. That's why I want tanks to begin with, less work between vaping.
How about the signature thing?
A cartomizer is an atty and a cartridge combined. As far as the signature thing, what type of signature are you looking for? There are various ones. Try clicking on one you like and see if it takes to to a link where you can make your own. Not all will allow you to do this...and I don't know what your wanting, sooo......
