Just started vaping a couple of weeks ago. After trying some disposables, I bought a kit Ego-T upgrade batteries with Stardust clearomizers. I thought the Stardusts would last me a few months, but after only two weeks of light vaping, the coils seem to have burnt out on the Stardusts. I'd rather not buy the Stardusts again. Any recommendations on tanks, cartomizers, etc. for a newbie like myself (something that lasts me a few months worry free)?
