Hey ..its me again..more nooby questions. Been using the alien vape for afew days now and really enjoying it. Im looking into MTL tanks to try, im kind of on a budget for now so my options im thinking of is either the aspire k3 (but dont like the bottom fill idea when out and about) or the nautilus X (coz its got top fill) and fact you can fit the larger bubble glass but the nautilus is kinda top of my budget , i like the idea of saving on coil life and amount of juice and not botherd about cloud vaping so no to sub ohm tanks. Would the k3 be ok or will i get cheesed off on the bottom fill tank. My head says k3 but heart says nauty X. Pods have been mentioned but I dont really understand pods ..is there a one that fits the alien or is it a diffrent set up, ie pen style .
