Unfortunately my only other mod is a vaporshark rdna 40 and the Morph doesn't work at all on it lol. I had it working again a bit yesterday. Basically loosening and then tightening the tank, or pressing down on it allowed it to make a connection. I should add, the subtank and Atlantis adapters seem to be working fine but it's such a pita to change from rda to other adaptors I haven't really screwed around with it muxh
