Is this with the Atlantis? I'm assuming so, but I know sometimes people use the coils in other tanks. This isn't DNA200 specific, but I was talking with someone who's done a lot more temperature control testing than me, and learned that pressure fit 510 pins like on the Atlantis, can cause slight resistance fluctuations while vaping. I later saw it mentioned on a live vape show, in a similar discussion. There seems to be a problem with sub ohm tanks with RBA coil head decks, and I assume could also be with the prebuilt coils. The more accurate the device is, I'm guessing the more susceptible it is. On the Vape Team (I seem to recall episode 24) the guy (Jaquith or something like that) mentioned a trick to get sub tanks with pressure fit 510 pins to be much more stable, I believe it was a bit of sanding. If you like vaping the Atlantis, it might be worth trying the temp control trick to get the pin to be more continuous and stable, if it's something easy that works well. I haven't done it and can't attest to what methods improve it or what tricks aren't worth the trouble, but I figured I would share in case it helps you with a topic to research into a bit.[/QUOTE]
I'm actually using them in a ehpro Morph. It's working a bit better now. Lots of vapor just not very warm at 530f lol
