Moved from carto tank forum to clearomizers forum
Unfortunately, the heads for most clearos are proprietary to only that type of clearo, even when made by the same manufacturer (for example, the regular aspire line vs nautilus vs atlantis, all by Eigate I believe and all different heads). There might be a couple that are cross-compatible, but I'm not aware of them off the top of my head
It would be nice if the industry could standardize their designs somewhat to make more things cross-compatible, but I don't see it happening anytime soon, unfortunately
