This is my first experience with vaping products & I have found using the Vype ePen3 to be both pleasant & hassle free. The operation of the pen is very easy and intuitive, with no mess exchange of the pods. There is virtually no maintenance, except to swap the spent pods for a fresh one & charge the battery. I bought 2 ePen3 units for my use, charging one whilst using the other. There is a nice range of flavours, which come in various nicotine strengths. You will find that the most commonly stocked ones in supermarkets & garages will be Dark Cherry, Blended Tobacco, Wild Berries & Crisp Mint. All the other varieties are available online. I have found that I get the best use of the ePen3 whilst I'm in the car as its safe to use when you're stationery, without having a lit cigarette to deal with. As I have recently stopped smoking, I have found that this system works for me. No cigs since 2.1.19. I can recommend this product, but you'll have to suck it & see for yourself. Happy Vaping.
