I originaly purchased a mini vivi nova from gotvapes and loved it until about three weeks in it slowly started leaching liquid from the bottom )where plastic meets metal). It was ever so slight. It made the tank and battery feel greasy. Then it got significantly worse so I emptied and cleaned it. I then ordered the smokey replacement tank shell from GV and immediatly noticed the same issue. I did a little research and found there is a supposedly newer 2.5 version that resolves the issue. Your site states the tanks have a newer shell that wont leach liquid so I pulled the trigger and orderer another one from you. I have my fingers crossed because I really like this tank when it is not leaking. I feel the o-rings a suspect. Please reassure me that I am not gonna receive a strike 3. I never overtighten and take good care of my vaping products. Any feedback is appreciated. Thanks.
