So I just went out and bought a Kanger Protank 2 today and have been using it without issues on my old eGo-C Twist and when I try to use it with my Vision Spinner II I get no vape from it and a very hard pull, as if there's no air getting through. I'm not sure if I'm missing something or if the tank just isn't compatible with the battery... I'm very concerned as the eGo-C Twist is my backup and the Spinner II is supposed to be my main. What could be going on?
