Having tried two different e-cigs and not been happy with either, I tried Vype E-pen. I just wanted something simple, small but efficient. I have been more than happy with the ease of use and length of battery life. I only vape in the evenings and one battery lasts me for 2 nights. I use the blended tobacco and I wasn't overly keen on the taste to begin with (not tobaccoy enought) however, I have got used to it and really like it now.
