Good flavour choices and nice design but the product loses two stars for the battery life which is just dreadful. I bought two batteries and one of them needs charging every day and I only refill the tank once per day. The other battery fairs slightly better and helps produce more vapour than the other which makes me think there may be some quality control problems. I will probably try a different brand purely on the battery life alone. Don't mind having to charge every two days but the loss of power from one of them after less than a week has made me lose faith.
