I just but some replacement atomizers for my janty dura and im having trouble getting any flavor from my carts when I draw off it. It tastes like metal instead of coffee or red bull. Is there something I need to do to the atomizer first. My original atomizer does not taste like this. Also it is leaking sometimes on particular carts like my red bull liquid. I have a fresh battery going, cart is not topped off, and i am doing a slow soft draw and i am basically drinking it. Could this have anything to do with atomizer? just a little confused that this is just happening on my new ones. Could it be a matter of just breaking them in? please help. Thank you
