I brought the quad and tri core ni80 fused claptons inner diameter 2.5 and 3.0 mm , for my destiny rta . They work a treat and fit nicely into this rta . Easy to work with and great flavour . Also seem to clean up easily for a bit of extra life of the coils being nichrome this helps and has some advantages over kanthal depending on your preference and how you like to vape over all pleased with coilogy coils so far .5 out of 5 stars.
