"The cheap ones" isn't very descriptive or narrow. Some are far better than others and may suit her better. "haven't worked" also may show unreasonable expectation. To me, "working" in the sense of someone starting out means something they actually enjoy. There is no need at that point to see how or when it will replace smoking for them, only to see it's something compelling enough they'd like to keep doing it and it won't fall by the wayside. Sometimes, it seems, that requires something impressive, sometimes just good. Good juice helps, I actually trace my bug back to a disposable running out of juice before battery that I refilled with a friend's chocolate-menthol mix, it was excellent for about half an hour and actually almost 2 years before I considered myself a nonsmoker.
Nautilus and a small mod is highly recommended.
Of all the semi-cigalikes, Juul is has been reviewed as very much like smoking. Expensive to use. Of other cigalikes, menthol does help.
I would choose a single coil (original) EVOD with a battery set to 3.4-3.5V (Kanger or clone), 2.2 ohm coil (Kanger only), with Goodejuice Patriot 12 mg. Cig/cigar flavor that's KILLER in that setup. Cheap, cheap-ish coils, takes some practice to get the draw right, sometimes a bit troublesome but small enough.
The Subtank is also highly recommended, I don't get it but many have reported they couldn't completely start smoking until upgrading to one or something at that level. Could be too much/ too unfamiliar a draw for her.
