For me I was looking for a new vaping experience as was fed up of messing around with coils,but I was disappointed with the vype epen 3 it was a great taste straight off but after a day the taste was not there. It would also be nice if you could see how much liquid was left in the cartridge. I also think the cartridge's are a bit expensive compared to e-liquid bottles. I don't think I will bother buying any more. But if you're just starting out I actually quit using the original e-pen and I was smoking 30 rollups a day and I haven't touched a cigarette in two and a half years now.
