Thanks for the heads up !!! I have no intention of sub-ohm, just thought it was worth a mention and apparently very well may be for general knowledge !!! Out of the box ... 5-wrap @ 1.57ohm (according to the mod) and that is just fine with me.You should ask around and check my memory on this but ... ~Zen was/is really safety conscience ... I seem to recall the Z-Atty has a spring designed to collapse so it might not be suited to sub-Ω coils.
I'll eventually try it on a 2.5 of course. Just easier to work the TC60W display and get it dialed in as I "learn how to vape" LOL. ... my 2.5 and minis all have the P3 conversion tops. That's why I got the Z Atty-U instead of the Z Atty Pro. On my 2.5, I'll have to use the Provari 510 adapter rings. I thought about picking up a bevel top 2.5 and ordering a Z Atty Pro but realized there still wouldn't be a guarantee the wick and fire button would be in a position for a nice comfortable natural hand grip. There were so many considerations and over-thinking going into my decision on which to get LOL. I honestly think the very best mod for the Z Atty is one of the HoH mechs with a bottom fire button. That way it doesn't matter how the coil is aligned. But I'm afraid of mechs. Even the gorgeous ones HoH has.
