I hate my Evic. I got the evic after not being sure of the safety of my mech mod which I love. I purchased a new body, end and top caps, 2 IBT tanks, vision aurora and more cartomizers and atomizers than I really want to discuss. The problem is my Evic only sometimes vapes. Initially I thought it was the vision aurora and that was just not compatible so I purchased other cartomizers (some pre-punched and slotted, some punched and slotted by me) all in a range of 1.5-2 ohms to test what would work and what wouldn't. It seems as if it will vape a carto or atty the first time I put it on. However, if I take the tank off to refill juice, clean or for any other reason it just stops vaping. The screen displays, the sec. timer runs but no vapor no matter how hard or loosely I draw. Seems as if it happens a lot faster with the 1.5-1.8 ohm but, happens even with my 2 ohms eventually. Each of the cartos or attys that won't work on the evic will work on my ego. I tried changing the voltage, no vapor. I tried changing the wattage , no vapor. I have switched batteries and with the new body I am using the AW 18350's. I'm super irritated and just need a solution so that all the money I have spent is not a complete waste. Please help.
