Slide on over to DiscountVapers and grab yourself a couple of E1-V Clearomizers (LR or SR versions). They are the same price as the Vivi Nova Mini, have better flavor due to fluffier wicks, look better, hold more
juice, and they have a sleeve/collar that covers up the ego threads attached to the tank for free(which is win).
When I was
vaping Stardusts I would frequently get juice in the battery's juice well. It was caused by one of two things, but all came from the same area.
1: I added too much juice and covered over the wicks. This causes juice to flow down the atomizer tube and into the well.
2: A crack in the tank cause back pressure and pulled juice into the well. You can tell if this is the case because you will see bubbles when you vape.
The problem is the slot area around the wicks. It can drain your juice straight down, no problem.
