Hi, I have a Vype E-pen which I have been using for several months now. I have noticed with the cherry flavour I am basically wasting more than half the cartridge because it begins to taste quite awful, as it does when you reach the end, although I have only used roughly 1cm of the cartridge. I don't know if I have had a faulty batch or something as previously I have had the cherry ones and they have lasted far longer? I am reluctant to buy anymore though as it is such a waste, 3 of them have been like this now, all cherry. The tobacco flavour is fine though so I doubt it is the E-pen itself causing this. Can you make a suggestion to me about what is best to do here? I can send one back to you but I have thrown away the other two, I will need to order more cartridges very soon but am undecided if I should change brand due to the fact I have had to waste so much of the cartridges, and thusly my money. I look forward to your reply.
