I have tried a number of different vaping devices and settled on the Vype e-Pen for it's all round ease of use and consistant vapour and nicotine delivery. No hassle, no mess, vaping made simple and practical just the way it should be. This said, there is always room for improvement; looking forward to the arrival of the 1000mAh battery and I believe there is room for a premium (Vype e-Pen Pro?) device with a more premium feel than the soft-touch plastic currently used. The blended tobacco e-Pen caps are perfect for my needs if a little expensive but these will hopefully drop in price as the devices gain in popularity...
