I progressed from others "e-cigarettes" to the Vype e-Tank because I wanted to try liquids and then to the e-Box because I wanted more control - and because the e-Tank batteries are so awful. The e-Box is definitely better but it would be nice if the mouthpiece was plastic so I didn't feel like my teeth were going to break, and that it were possible to get more smoke. I love the range of liquids though im not all that adventurous with flavours (but thank you for the melon. :) All-in-all though, I think I've more or less found my sweet spot both for cost and convenience.
