Ok so u have to post five times here so I figured I'd start off by saying hi and that started vaping in August of 2014. I use a sigelei 150 and right now an arctic that's driving me crazy enough to join ecf to try and figure out if anyone else is experiencing what I am. I put in a new coil and it's working great. I refill my juice and then it tastes like ... and a little burnt (not burnt like coils dead just the juice tastes a little overcooked) mind u each time this happens the coil is at most 3 days old
