The new ePen is great, the new way in which it charges it's genius no longer do you have to mess around taking out your cartridge refil in order to plug in your battery which is really handy especially when charging it in your car... However one draw back I found with the old model and again with the new one is that according to Vype 3 ePen refills are the equivalent of around 1000+ puffs and with the ordinary cigarette being around 20 puffs that's a lot so you'd expect them to last longer and be more cost effective at just £6.99 for a pack of 3... Well you'd be wrong because the fact is you'll keep puffing away and before you know it it's 3pm and you've already gone through an entire refil (which ought to be around 300+ puffs worth). Not sure if this is possible but a really good way around this would be to have the ePen shut off when the average amount of puffs one would get from a cigarette is reached. For those using the ePen or any other Vype product as an alternative to smoking cigarettes this would be a really helpful feature.
