I absolutely love temperature protected vaping. I currently have 4 DNA40 devices and all have nickel builds. A little tricky at first with the soft nickel but once you get it, it pays off in spades imo.
Here's my Ni200 build on an Erlkonigin. 28g, 10 wrap, 3mm mandrel. 0.14Ω. Wicked with Sally's cellucotton (rayon).
