I've got 2 of the new Ego Cs Type Bs with the 2 ml tanks, and I love them. I haven't had a problem one with them and they deliver great flavor and vapor. In fact, they deliver better flavor than anything I have, including my VV Mod. I've had Ego T tanks before and learned how to get the best out of the tanks. One thing that hasn't been mentioned here is not taking the caps off of the tanks and filling them through the hole with a syringe. You can get the level of the top of the juice just perfect so that air bubble in the tank will work for you. It's less wear and tear on the tank, and I think it results in overall better performance. The tanks should fit tight and SNAP into place for a good seal between the tank and the atomizer spike. Personally, I've never had an issue with the wick placed improperly or too long or too short. As others have mentioned: slow and easy draws result in greater flavor and vapor with less problems of any kind. Bluntly, I think that the Ego C type B is a winner.
