The Vype ePen is a clever, convienent and simple e-cigarette. The design and basic idea appeals to me because the capsule system does away with drip feed bottles of liquid. The cap also contains the heating element which improves quality and performance every time I use a new cap. The customer service experience is also excellent. However, there is room for improvement in the Tobbaco flavor which I believe could richer taste and smoother. The caps do leak when drawing on the mouthpiece and a bitter taste is experienced. The rubber mouthpiece although the right shape does taste like sucking on a pencil eraser. The ePen is great idea, but is still a beta version still in development.
