I'm a couple months into this, I have my set up that I am happy with. Mvp2 and a mini nautilus. Now my wife has decided she wants to stop smoking too. Great for her better for me. She took my beginning spinner battery and aspire et-s tank and set off on a quest to find a liquid she loves. Now I'm up to my eyeballs in 3/4 full bottles of juices and 7 extra ego style tanks laying around on any avalible flat surface in the house. I know this is a bonus for me but I'm not sure how to handle all this etra juice in tanks. If they are not vaped right away do I need to dump them out and clean them? How long will liquid last in a tank? Are they going to leak? Do I have to worry about the treads wearing out on my mvp because I keep changing tanks now that I have all these new choices.
