Pros: Coffee flavour does taste like coffee; each refill lasts much longer than the VSavi brand I've previously been using and which, over time, seemed to have been subject to manufacturers cutting down fuel content; Smoko service is fast and person on other end of phone is friendly, helpful and unbureaucratic; kick at back of throat is just right; cheaper than some; have only had one dud re-fill so far. Cons: packaging is murder to get into; beneath the coffee flavour there is that familiar, not very pleasant e-cig undertaste which, for some reason, is more noticeable when outside; I may be getting used to it by now, but when I first vaped these I started feeling a little ill; have only tried one other Smoko flavour: vanilla, which was gross; re-fills could be cheaper.
