something cheap and simple is the ijoy solo elf kit.. no tc modes just wattage, up to 75 watts, comes with a MTL tank... very comfy to hold takes 1x18650 and uses ijoy or nautilus coils. Has the taste control option which is why i like the mod itself, kind of a tc mode for kanthal.. and although not perfect it actually does prevent dry hits.
Of course there is the nautilus 2 zelos kit with built in battery. Great little 50w mod but be aware, the nautilus 2 0.7 coils SUCK big time, kind of like the 1.2 mini triton coils suck. Little vapour at lowest rated wattage, but any higher and it's burnt city. Of course you can use elf coils, mini triton 0.15 nickel coils, 1.8 coils, bvc etc..
I still think the nautilus is the best get off smoking thing around. And to be honest, the nautilus 1 full size or the beyond vape silo tank would be my recommendations, with your choice of mod. Reason being they have a large 22mm tank without these very silly TPD regulations, and she won't be filling it as often. it is bottom fill however vs top fill for the others i mentioned.
Then there are really simple things like the aspire K2 kit with the standard bvc coils. it just works and it's tiny. Good throat hit, use with high nic.
Plenty of options.
heck, if she likes the feel of a cig, why not try a cig a like or pod system?
I tried everything to get my dad off the smokes and i finally succeeded with a von erl my pod system. Now there are heaps of pod systems around, some refillable some with flavours.
I have heard many vapers say the easiest way to get off the stinkies is just get a juul with the snap in throwaway pods.. again, many many options...
so are you looking for mod and tank, or pod system, or does it have to be a rebuildable? can't help you with the latter. If you want to try a cig a like, i recommend the cirrus 3 kit from white cloud, not the 2 and not the 3X but the 3.. they have like 25 flavours and go up to 5.6% nic, no one else does that. They have low nic too of course.
