I hope it works for him! I recently tried to convert my friend who quit smoking with me. I went back to
vaping with 0 nic to keep the monkey off my back and she wanted to try it cause she was slipping as much as I was. I gave her my RN4081 and a bottle of TV banana fosters doubler. Despite my advice on how to use it, she just can't seem to get the hang of it and wants to give up. I even offered her a couple of my 510's to see if she liked it better. I'm afraid she's gonna relapse soon and go back to analogs.
So I really hope your friend sticks with it,
