@AvaOrchid the most you'll need with the X is spare tank sections, o rings and the screws that trap the wire.
Also we wanted to know how your getting along with the X after the honeymoon?
Also I have confirmed that the X can fit 3mm ID coils, you just have to use some Jedi skill and force your coiling tool down in the notches. It will fit, honest.
Also soon I will post the correct o ring sizes for the X in the Coppervape Hussar Project X thread, as have you been annoyed by trying to remove and replace the top cap?
