I think you did pretty good. I've been through many devices that, for one reason or another, are now collecting dust (Ego's, sketchy mech clones, supposedly nice "authentic" mechs..)
If I could've, I woulda skipped all the nonsense and gone straight to what I now know is my most reliable, most preferred method, which isn't too far off from your device tbh.
Worst case scenario you wean yourself entirely off nicotine, get bored of vaping, and sell the devices/pass them onto someone else who's trying to quit. Doesn't sound too bad, really.
