To OP, I feel your pain. Started with a 901, then a Blu, then a 510, then a VGO, then a couple of others. Now have a Provari. What can I say, it has revived old juices, and attys. Spent my time with dripping cartdriges, cartos, ce2s, fluxos, sapphires, tank mods,and t-tanks. Found my sweet spot, Vari with various 510 attys, or Vari with tank. Golden. I have been vaping for about 1 year. It's been a journey, much money spent. But my health is better. And I spent less then on smoking. I was a 2 to 3 pack a day smoker for 23 years. Vaping has been the only thing to get me off analogs. That is worth it to me. JMHO
