“I'm quite new to vaping but not so new (or so dumb) as to not see the savings and safety of filling my own tanks with trusted CBD vaping "oil" ("oil" is in quotes because especially now it's important to understand that PG and VG base CBD vaping liquids are not oils, ie, NOT like the Vitamin E oil used in some street THC vape tanks. I love the infrequent ritual of filling my tanks with different CBD oils and your tanks seem to all function identically.”
