What e-liquid should I purchase?

There is no one-size fits all answer here, so the best thing you can do is to try out a few e-liquids and see which one suits you. Interestingly, don’t assume that you need an authentic tobacco flavour. There are some good ones out there, but we find that the vast majority of vapers end up choosing a flavour other than tobacco, and this happens very quickly if they try a few different ones to begin with. In terms of PG/VG, you’ll have to try for yourself and decide what you like.
