I bought new "kanger tech coils for protank, evod, and unitank" for my protank 2 and I checked if they were real and they are, but it doesn't seem to fit in my protank, the coil doesn't come out far enough from the tank and my istick 20w & my X6 Variable wattage battery can't either. I spent 20$ for 4 packs and I can't use them, I've tried 4 different could already, can anyone help?
