I have just come off smoking and I thought using an e-pen would not act as a good alternative but over the last month I have been proved wrong, it deals with nicotine cravings fantastically and haven't had the need to smoke since. On a side note, I'd like to say the customer service I received was simply outstanding. My product did not arrive on time as the courier I believe did not deliver to the right address (no fault on Vype for this by the way). Anyways the product was eventually dropped off, but it is worth mentioning how committed the team at Vype are to ensuring that my product arrived (special shout out to Tony), they were consistently chasing up the courier on where the product went and kept in constant contact with me throughout and were extremely friendly on every call with them. Perhaps the best customer service I have received from any company. Could not recommend them enough. Overall, glad I stopped smoking!
