Hi there everyone, first time poster here. I'm not exactly too experienced with vaping, been using a Volano Inferno for over a year now and I'm not really happy with it. It constantly leaks and the vapor production varies day by day. I was reading around the forums here and seen a lot of people talking about the istick 50w battery and I was going to pick that up. I was wondering if anyone had any recommendations for a good atomizer to go with it. I've read the Delta II is pretty solid. And another question, with an atomizer such as the Delta II what kind of routine maintenance/part replacement will I have to do? For example, with my Inferno the heating coil burns out after about 3 weeks of usage and I have to replace it. Is it the same kind of situation with the Delta II or other atomizers? Thanks in advance.
