started out with a nautilus mini when i first started vaping for the first few months, and also wanted something to rebuild so moved on to a few different tanks like the kayfun lite which was good but now using a erlkonigin clone which i love once i was able to get the wicking right its the only tank i use at the moment. it comes with a polycarbonite or whatever tank, so purchased a few glass tanks from ibtanks that fit well
