Very happy with purchase! I've been using e-cigarettes for a while now, and decided to give vaping a try. The Vype e-pen is very easy to operate: 1. no need to unscrew batteries when you have to recharge, just use the usb slot at the bottom 2. very simple to use, with a choice of strengths every puff 3. easy to change refills, no need to wait until one's finished, you can swap them round as often as you want 4. really REALLY leak-proof, no seepage at all 5. wide range of both flavours and strengths. So far I've tried tobacco, mint, indigo (blackcurrant) and vanilla - and I've not yet found one I don't like, although VANILLA is definitely the favourite so far! The only way to improve it is to reduce the price of the refills; they're fairly competitively priced, but a few special offers would be welcome. Overall: 10/10
