Finally got my mutation x2 RDA by post this week so built my first dual coil with nickel 28AWG.
I know it's not the tidiest but it vapes beautifully
Quad coil next
Any reason you used holes 1 and 2 then 3 and 4 and not 1 and 3 then 2 and 4, the coils would be a lot more centered. Other than that it looks neat enough.
