Hello, I just received my e-cig from aquavaporcig.com. It seems pretty cool to me, I purchased a 510 PCC kit. My question is, how in the world do i know which cartridges or cartomizers are compatabile with my device? Im just asking because I think i'd like to experiment with a few other brands. I do have some menthol juice, and im clueless on how to use that, but i will look into some posts for that info. Or am i better off just buying empty cartridges and shopping around for a flavor juice I like? I really appreciate the help everybody!
