The mini tanks are fantastic and there is no comparison to the cartos. I love the full flavor, the hit, the amount of smoke, etc. I quickly switched from carts to the mini tanks; however, I cannot seem to get more than a few days out of a mini tank before burning my juice. I tried cleaning the tanks in water as suggested in a YouTube video, to no avail. I know they are cheap compared to packs of analogs, but $3.99+shipping online is getting a little ridiculous. It appears that I need to be more mindful about keeping the wicks moist in the future. So, my question is, is the mini tank shot once I start getting that burnt taste, or is it just a temporary condition that as long as I start making sure the wicks are moist I won't experience it?
