My girlfriend had a setup that was ok, like she didnt take care of it because she didnt really use it... she wants to quit and all but just never kept up with it. So i showed her every where I get my stuff from and she was excited, but I knew she wouldn't buy it on her own. So I decided to buy her a nice set up and a case too for her to keep in her purse etc (her previous one had things floating in the liquid in the tank... yeah...) and I was thinking Xmas gift. But then I thought why wait? she wants to quit badly, so I told her about it today when it showed up and just made it a just because gift. I went simple with a few packs of clearos, 2 400mah bats and a bottle of liquid that I know she likes, 2 little sample packs of liquid plus the case and the lil eGo suction cup holder things (which are really great by the way). Total around maybe $60. She's super excited.
So I would say yes, good idea for someone that wants to quit and go with vaping. but keep in mind if they dont know much about vaping, they'll be looking to you for help etc so be sure to give them places to get supplies etc. having a local shop around may be helpful in keeping them to stick to your gift to them, especially if they need to find a go to flavor to vape.
