used my tank for a couple days now and love it. no leaks have even used it a couple times with my auto batts. i will note that with the auto batts i don't like having control, as it shuts of after i take a hit which i think may cause burn res build up. i can vape all evening, and it's like a fresh carto every time. i've cut back so much i didn't even use it fishing. in the evenings i feel the need and it fills it fine. might pick up a couple more. i will note i am going to kick this habit one day also mainly for money. for now though it is saving me money and helping me on the long road ahead. i still get cravings for analogs i just want to lite one up. i see i as i've gone the farthest i ever have no point in waisting it. soon i will be reducing nicotine levels and see how that goes.
