I have used the Vype e stick and pen for a year and I would like to say that they have really helped me to drastically cut down the number of cigarettes I smoke. Of the two products I prefer the e stick as it closely resembles a cigarette. I use the blended tobacco flavour which I find very pleasant. However, I have a few little gripes. Last year when I started using the e.stck the product was extremely reliable but from May 2015 the e stick tips seem to have deteriorated in quality. I have had some packs where each tip was a complete dud and in general the tips last for only a few hours. I am also rather disappointed that I have not been able to purchase replacement batteries for some time.
