I don't own an XL (or an NXT), but I have an OG E-Nano from 6+ years ago.
It has, and I think this is by design, a relatively loose fit to the stems … "relatively" compared to the sort of tapered/ground-glass stems of (say) my Milaana. I have read these concerns about the fit on the XL and wonder if it is also just by design. (I am procrastinating on my second Milaana repair after those tighter-fitting ground-glass stems have again popped the unit's internal glass, so maybe not the greatest idea … just sayin'.) I think a lot of glass tech in the DHV world uses those tighter-fitting stems, and perhaps people are just not used to the idea of a looser fit.
I would definitely give the XL a chance before you give up on it, maybe write to EpicKai or message the company reps here (
@nadia_epic and "Andy" =
@ACE OF VAPE ,
though I can't find his username right now *) about the "loose fit", as I don't think they've ever addressed it on FC. But it could be entirely by design.

Regarding micro-dosing, I usually do about 0.03 or less (< 1/30th of a gram) per stem, though I usually do 2-3 stems at one sitting (compare & contrast flavors!). I am entirely, perfectly, completely, abso-
fucking-lutely satisfied (no; really: ecstatic!) with my OG at that load level, and have been using it 1-2 times daily for almost all of those 6+ years (little week's vacation every year or so). I get brilliant flavors and wonderful effects—and my stem is "loose" (I tend to twirl it while I inhale, in fact.)
If you stick with the XL and are bothered by the "looseness", people here have highly recommended JoDa Glassworks' WPAs as tight-fitting and righteous (and they certainly look nice in the pictures); see earlier in the thread.

But I would recommend trying the XL to see how you like it before you give up on just because of stem looseness. (Start at lower temps and go up slowly, if you have the patience. And buy an extra stem or two for compare-and-contrast: just sayin'!)
In any case, I hope your purchase works out for you, and I'm almost certain you will be happy with your E-Nano … one way or the other.
