I bought a Smok V8 stick for my friend, and then we were supposed to change tanks because he likes mine better. I am vaping on the Relaux rx200 mod, and i'm using the Ijust 2 tank. But somehow, when i put the Ijust 2 tank on the Stick V8, it won't work. Do you have any idea why? I am using 0.5 ohm coils in the Ijust 2
