e-cigarette advice? Buying a kit as a gift.

[Matariki]

I want to buy some kind of starter kit for my sister for her b-day. She knows I'm doing this.

The little bit of reading I've done has me worried about buying one that has a short battery life, or other problems. Would like to find something that looks pretty much like a cigarette, doesn't taste gross, and is made well enough that it won't break or be too inconvenient for her to actually use.

I frankly don't want to have to do a ton of research, but would love to hear specific brand and model recommendations people have used this. Also which one's to stay away from.

Thanks in advance!
