Ima go out on a limb here and say, thank god that's over.
Thanks for all your hard work in this Jason, you earned a loyal customer in me because of this issue.
Back to reality, I seem to be having some trouble finding AW IMR 18490's that clearly say nipple top, most don't say anything and it is hard to tell if it is a button top or what. Are they all nipple top? Do button tops work in the ZNA?
Also I know this has been asked but any news on the 18650 tubes?
