Hey friends, My cheap e-pen came and I'm in love with vaping. Hubby is letting me order Kroma A Mod with Zenith Tank Starter Kit by Innokin I want to buy extra coils while I can but I'm clueless. This goes to the Innokin coils, I assume I need to use their brand. Innokin I hate paying for shipping so I have to do some add-ons that I will need anyway so I best get the right stuff. If there is anything else I need please let me know. Oh, I'm not sure if this has a replaceable battery or not, if so what one do I need. LOL yes I'm excited. Thanks bunches.
