I've been using the mega cartos for quite some time and recently tried new juices from AIV. Everything is tasting horrible. Tried a new cart and let it soak for 24 hrs and still no change. Has any one else had any issues? I've heard amazing things and I can't taste any of it. 1.7 ohm single coil 1.5 dual carts syringe injected and still no change. Am i missing something?
