Just started vaping 3 weeks ago after i got my Ego C Twist Vivinova ordered from China. I dont know if the tank is spoiled or is it normal. when the liquid is in the vivinova tank, i cant put my tank sideways as the liquid will leaked out from the tank. When i put it inside my case, my case will get oily because of the leakage of the liquid. is it normal? i just have to put it straight up so that the liquid in the tank wouldnt leak ): any suggestions? should i buy a new tank?
