I spoke too soon on the H+. The first coil burnt in 3 days, 0.4 at 65w.
When I changed it, the top of the 3 piece coil unscrewed, leaving the rest stuck in the base. Not sure how to remove it.
Anyone using this tank, be sure all parts of the coil are tight before screwing it in. Not something I knew to look out for.
So for now, I'm back to the og Herakles. On occasion, I've needed to mess with the copper 510 pin to make contact.
Sense is not exactly making my day.
Got the H+ on eBay for 19.99, and it was the coil that caused the issue, so I may be SOL. Live and learn.
