Recently my 2 Tobecco Super Tank Mini tanks won't sit tight on my Vaporesso Gen Mod. It doesn't spin, when it's all the way tight but they both wobble a little while on the mod. It's kinda annoying & I try my best to keep my thumb against the tank just to make sure it won't move while firing but just wanna make sure I'm safe to continue vaping as I can't afford a new tank, definitely not a new Mod right now. On the other hand, I have a daughter to take care of. Just trying to figure out if it's fixable & tanks or mod? I hope I explained it well enough?!
