I have just changed from the Vype ePen to the Vype eBox. There were no complaints about the ePen except for the lack of flavours available. I have been using the eBox for about one week and I love it. The battery has 8 bars and after a day of using it, it still had 7! I have been smoking for 35 years, approximately 25-30 per day and I am happy with the kick in the back of the throat. I also like the satisfying 'Darth Vader' sound as it crackles. The soft rubberised finish feels lovely to the touch and it is a perfect fit in my hand. I haven't seen any difference between the airflow open or closed, not that it matters. Maybe it could go into auto sleep after 10 mins like the ePen instead of 15mins? I really hope Vype bring out a case to carry spare vaporisers/liquid, otherwise I could just buy another brands case and use it. Due to a lack of case I will mark the eBox down to 4/5
