I bought an E Pen starter kit at my local shop in an effort to stop smoking cigarettes. I found the E Pen very affordable, neat and tidy, no fiddling with oils or having to dismantle the device and I had a choice of replacement caps in different flavours locally. I then got the E Pen3 through the govype website and found all of the benefits above with the added satisfaction of a smoother more fulfilling vape. haven't smoked a cigarette since. A brilliant piece of kit!
