Hi, I loved the vype e-pen when i first got it, but after using it for a month i had to stop as it seemed that the liquid was burning even when i had a full e-liquid in it? Also the liquid has been leaking as there was little dry bits of the liquid all up the inside of the pen and on the mouth peice. Overall it was a good product to begin with but just feel let down as of all the problems i have been having with it. Would still rather use the vype e-pen than other products on the market at the moment as i love the design and it is very easy to use and change e-liquids. Hope to hear from you soon, Thanks Graham Macfarlane
