RPM2 coils

[GraemeKirkwood]

I think Smok must outsource their coil manufacturing after a couple of months or something as their coils are always great for a few months after a device has come out then turn crap, so you might not necessarily be doing anything wrong. Apart from the above advice I believe Coilology/vapjoy did rebuild kits for the RPM2 so my advice would be to just give those a go instead.

This could be true. I had a Nord 2 and was using the RPM coils, first purchased when it was released. 0.4 coils were the butter to my bread. Exactly what I was looking for in a vape. Now, if I buy the same coils, I get two or three tank worths out of them MAX, no matter what juice I'm using (2ml capacity)
