I just picked up my first tank in almost a year, after solely rebuilding on RDA's. I got the Herakles Hydra, and a pack of the nickel coils for it. I was wondering if there's any difference between the Hydra nickel coils and the regular Herakles nickel coils? Like are they compatible? Just figured I should ask.
Thanks for the help in advance,
