Just wondering if others have noticed any difference in the quality of taste when they refill a half empty tank? I can vape from my EVOD and then top it off and the very next hit tastes more refreshing. I know that there is no way that the fresh juice has wicked that fast but it seems to taste fresher. Would it have anything to do with less air in the tank or is it just psychological? It's just not with my EVODS but with other type tanks too.
