I enjoy the product and it's convenient to buy online. But the delivery time is not too good. Also, I do resent the fact that the cartridges can't be refilled. They run out in no time and then that's it. You have to buy new ones, and they aren't cheap. A small bottle of e-liquid would refill them at least twice and costs about half the price of the prefilled cartridges. Makes economic sense for Vype, but not I think for the consumer.
