I'm looking to buy either a dna or IStick to use with my kayfun as a daily vape. I'm planning to take it with me in my car to different places, so portability is kinda big for me. As of right now I'm not into dripping (tried it but didn't like constant having to put in juice). The real big issue I'm having between the two is I feel like I'm not sure when I could want more power. So I'm kind of hesitant going with the IStick. Which do you guys think would be a better choice?
