That's an awesome gift! Careful w/Boba's--I hear it's thick. The eRoll does really well, even on dark, 100% VG juice, but it's an ego-C atomizer and will gunk up pretty quick. Then it's a little beech to take a drag off of. I have a bad bad case of TMJ disorder, and when the atty gunks up (it happens slow so you don't notice), my entire face hurts, lol. Just get him a couple packs of new ones or teach him how to clean it and it should do very well to get him off the stinkies.
Also, get the extra cone so he has 2 units. It's the only way it will work for him long term.
I used mine exclusively the first month and a half of vaping, and I chain vaped that mother. I still use it often.
