Okay so I bought a protank 2 yesterday. But even before that I was getting a weird taste from my juice. Could my pen be causing that or could the liquid just be bad? Everyone else that tries it says it tastes fine. But I think it tastes off almost burnt. I've replaced could twice and even put a protank coil in my evod tank and it still tastes off. I bought two extra coils yesterday along with the new tank. I'm vaping around 3.5 on a 1.8 ohm coil head. And I'm sill getting a tiny burnt taste.
