I don't know man... if you're about to
throw away a $25 atty, why not dry burn it and try it out lol? I think the only drawback to the HH is that tiny piece of wick inside the coil, if only you could easily replace that little piece after dry burning, it would be perfect. I've dry burned this HH357 here many many times (also pulled out that wick) and it vapes just fine. Its that piece of wick that gets nasty, not the coil.
In other news... on my genesis atties, a wick lasts me 5-6 months, and my
coils last me around 5 weeks. When I do the math and compare my results with yours... Nach is winning!
