Well I just have to say that Cartomizers at high voltage is now my favorite atomizer. Now I think that running at high voltage on old ones are not so great. Yet a freshly opened/filled cartomizr is a dream at high voltage. So much vapor, and the heat is really on them. I let someone try my Chuck with fresh batteries, and with a fresh Blue Berry cartomizer on top. I swear he took a 10 sec hit, and about hit the floor coughing on how much vapor it put out.
