Don't start vaping to quit. Start vaping to ditch cigarettes for something better (healthier, better taste, more convenience, perhaps even more nicotine). Buy the best device you can afford. Forget about quitting - enjoy your new experience: you can choose a taste, you can choose strength, you can inhale any volume you want wherever and whenever you want, you don't stink, your health is actively improving from the level set by smoking cigarettes.

And only as enough time passes (not less than some months) - consider quitting if you want.

That would work better. IMHO.
