I finally bought a pro tank II mini and it has been awesome! but I have a big issue. I'm currently using aroma eliquid (70/30) I believe and the first tank was great absolutely no problems. I then filled with more aroma (different flavor exact same mix and thickness) and it started tasting burnt out of nowhere. I let it sit to see if I was vaping too frequently and that didn't help. I pulled one flavor wick out and that just caused lack of vapor due to it absorbing too much I thought. I can't seem to find a fix. I'm at work but I changed out coil with one from my evod and it was great for about 20 drags and it's now burnt taste too. this is incredibly frustrating because I thought I finally found a happy medium. I'm using a standard ego battery.
