I have a number of cigarette devices and was interested in the Vype device because of its small size and easy pocketability. I have been very pleasantly surprised by this product. The combined carry case and charger means that I can go for three or four days before having to recharge. I also find the tobacco and cherry refills to have an excellent flavour and despite the very small size I actually find that they last for a very good amount of time. All in all I was expecting to be disappointed for such a small products and yet I have found it to be an excellent addition to my non-smoking tools.
