This is the kind of fault I was talking about.
(If you can't tell, the resistor shorted out to the unused and unshielded ground pin.)
Yes, the Groove suffering a meltdown is a serious issue, I'm just saying that all we have to go by right now is a few pictures, a video showing a slightly squished battery (which I maintain, is normal), and SMOKtech's word that they have a design flaw (or two). I just wish we had more to show us the what and why.
I wouldn't have gotten into vaping if I didn't think it was safe, most people would probably cringe at the thought of sticking a battery so close to their mouth.
But rather than continue posting in these threads, I think I'll just leave you guys to send your stuff back for replacement.
