I'm wondering if someone could enlighten me on why the hell it's so hard to find .5 non-rebuildable CL coils?!? The only luck in finding any is on EBay and the description starts out saying that they're not authentic! In case anyone knows I'm also finding it extremely hard to find the Joyetech Delta 2 LVC coils.... I ve had really great experiences with both of these tanks and would like to continue... It's kinda looking like I'm going back to the drawing board though... Thanks in advance to anyone that can help me out.
