Interesting input, i did got 2x vandy vape superfine mtl coils, i'll be trying them today cuz had no time this weeked, for my MTL RTA.
can you explain a bit more about your fact of its low quality cuz, i'll like to learn more.
About Coilology wire, well im regular 3core wires they make, is amazing, great quality but, all their wires tan green and a bit blue when dry fire it, the unique way im able to tan ni80 in a blue tone is when wash it and manipulate it with gloves or clean surfaces, cuz even the residues from oil your fingers can left on coils will affect the colors after dry burn it,
Regards,
