I have that mod too, and it's great, but keep in mind - you're gonna need a battery charger, 4 batteries, a tank, coils, and juice for this bad boy. You're probably looking at another $60 on top of the $60 for the vape itself, at least. And if he's too boomer-brained he might not be willing to futz with it if he doesn't like it, he might not try different juice or different strengths of nicotine or whatever. He also might not like carrying around the huge heavy box with a leaky tank in his pocket all day (and rare is the tank that won't drip if it gets upended for any significant period of time).

I guarantee that there's a vape store near you that has a decent starter kit setup that might be better for him to dip his toes in, and a nic salts vape (basically a very fancy juul) might be easier for him.
