I recently started and i got my evic vtc mini kit with Tron. I like to plan far ahead and after some thorough research i found out that my device uses some atomizer head and the coil within comes in CL-Ni, CL-Ti form. I am wondering isit legal to just ship the CL heads from joyetech anywhere online when my coil needs to be replace ? Bcos i found out that oni CLR type is rebuildable. Some guy posted around here he tried rebuilding the CL but had some leakages problems. Anyone that have experiences with evic vtc mini can provide some guidances like is it simple to rebuild the coil in CL heads which comes tgt with the kit rather than need to source for CLR heads which is extremely rare to get over here it seems?
