I have recently purchased the Vype E tank kit. So far I am very happy with it. Easy to use and to refill. The blended tobacco liquid that came with it is very pleasant. I'm still on my first fill after 5 days of use and it is also still on its first charge. The unit is very well balanced and also very discreet. Overall I think this is an ideal unit to use and will definitely continue with it for the foreseeable future.
