Hi guys! First post, but have been a lurker for the past few weeks trying to learn what I can about this new world of vaping. Currently it has been 2 weeks since my last analog and want to stay quit. I am currently using CE4 clero's and a vivi nova tank knockoff. My battery is a 1300mAh at about 4.2v at full charge. Which would be the next best buy, EVOD or Protank? I have found i can get the 5 pack kits of EVOD's for the same price of a Protank, is it worth it? Thanks guys!
