Been a smoker for 30 years roughly 20 to 30 a day. Bought the epen 3 days ago Haven't smoked a cigarette since. Tried everything over the years patches gum spray tablets the lot. NEVER managed to go more than a day before smoking again. The epen is a nice bit of kit easy to use lasts all day on one charge and easy to change flavours. Have since bought the estick for when I go out as it is more discreet same again easy to charge lasts a long time and easy to change flavours. Overall I am very impressed with vype products and I did look at many other different manufacturers of electronic cigarettes. What sold vype for me was the ease of use no coils to change no messy filling. Delivery was fast and when I received my order had a query about charging so rang customer support got through immediately and they were extremely helpful. 10/10
