Hey guys. I just got an mvp 20w, and my kanger suntank mini just came today. I know I can't use the .5 ohm one, so I'm using the 1.2 ohm one. When I first got it, I pressed the button for like a second with no juice in it. Then I put juice in it, it wasn't working, then I looked up what to do and primed it. It's just not working, so frustrated because I really wanted to use this. Thanks.
