The manufacturer may have slipped up on the house coded chip.

In one unit the chip was marked; 3417WA, in the other it was marked;
Esmoke33716M.

I couldn't find anything on the specific chip. I suspect it's custom
and well protected. This should help explain what's going on inside:

As for e-cigs and vaping, I don't indulge and see no value in
breathing fumes. However, a friends son got involved with the vaping
scene and has demonstrated to me that there's plenty of demand and
money available. They're generally banned in public places, which I
guess adds to the mystique. Judging by the consumption of 18650 LiIon
batteries, e-cigs have not only helped lower the price of these
batteries, but have greatly contributed to my growing collection of
half-dead 18650 cells. If you read candlepower forums or the various
e-cig forums, you'll find plenty of discussion about which batteries
are best (or cheapest). That gets my attention.
