Hi. I have been using an e-pen device for several months now, originally bought the pen and liquids from Sainsbury's and now buying direct from Vype as I am lowering nicotine content. I have smoked tobacco for 30+ years and finally decided to switch to ecigs. I have now been completely tobacco free for over 3 months and can honestly say I would have been unable to achieve this without the help of my trusty Vype device! I have just upgraded to the e-tank pro (on offer). Love the devices and great service from Vype. I think Vype would benefit from some sort of customer loyalty or membership club / subscribe and save to reward loyalty and offer some savings / discounts to keep us coming back. This would be my only suggestion! (Apart from targeting the 'hipster' market with the sleek black and stylish 'Vype Pype'! - missing a trick there Vypesters!!) Great products, great flavours. Great Service all round. Thanks Vype!
