I recently purchased an mvp 2.0 to upgrade from my c twist. Bought a few different tanks, smoktech udct tank, smoktech bottom coil tank, and a protank mini. Primed the carto, filled the tank and vaped for hours. Decided I wanted to switch flavors. So I got a different carto, did the same thing and now it just constantly floods. Did a lot of reading and realize there can be defects in cartos. So this morning I tried to put the carto that was working fine with the juice that wasn't giving me problems. Well guess what. That flooded very shortly as well. The only tank that isn't giving me fits is the protank mini. I am becoming super frustrated. Is it my mvp 2.0? I don't think I am doing anything wrong because my carto tank for my ego c twist works flawlessly. Any help would be appreciated. Maybe I should buy the protank 2 and be done idk!!!
