I've been vaping for 3 months now and I've been using a basic mini ecig. I am thinking of getting a different e-cig and I want to know if the Ego T is a good one to get? Is it difficult to fill the tank? I've been refilling my carts on my current ecig, is it similiar to that? Also does it have good vapor and does it have a long battery life? Sorry for so many questions but I really want to make the right choice. Thanks!!
