I am pretty sure I'm shelling out $30 to buy a vape on ebay, digital box with a whip. Free shipping! So, I've read elsewhere, vapes can die off pretty quickly. What are the cons of buying a cheap vape? How long would it last? How do I properly take care of it to extend it's life? For a broke girl like me working part time, I can't afford anything like a volcano and eat and pay rent and have running water and electricty. It just won't work.
