I was looking for an e-cig which required less maintenance as I was fed up of changing the clearomiser on my old e-cig. I also wanted an e-cig which allows me to change between e-liquid flavours easily without mess, whilst providing a great vaping experience. For all of the above the Vype e-pen fits the bill with the added bonus of a sleek and lightweight design. However there is a negative to the e-pen in that the battery life isn't as good as any device I have tried before. One day I had to fully charge it twice, even though I have had the e-pen for less than a week. If Vype sort the battery life they're on to a winner, but until then I may have to go back to my old one.
