I used to have a big, heavy, cumbersome square shaped tank e-cig. I liked it, but became embarrassed with its appearance, and didn't want to have to manipulate the e-liquid anymore. Bought the Vype pen. Pros: Smart look, discreet, easy to use, no need to manipulate e-liquid, very light, very easy to change cartridges. Very good customer experience during purchase (easy website, swift delivery). Cons: Not very powerful (if you have a variable clearomizer, you may find it disappointing), takes a couple of hours to charge and would only last 1.5 day. You obviously only can use the cartridges sold by Vype. That's alright (good quality) but the crisp mint one tastes virtually of...nothing at all (in 6 mg/ml). This was unexpected since I really used to like the crisp mint bottle e-liquid (for my previous tank e-cig). The other menthol one is only available in 18mg/ml (I am trying to quit nicotine), so might have to try other low concentration nicotine ones. Summary: good all rounder, no itchy throat, no risk of toxicity with e-liquid, or damaged coil, but not very powerful. Would love a stronger tasting mint flavor. ***** update: following this review, have been contacted by customer service. They kindly sent me a pack of apple flavoured cartridges for free. Very impressed by the swift reply and kind attention from the Vype team. And apple taste suits me a bit better.
