I had my Protank for two days before the base thread feel off. Anyone know where to find these? Every place I look at is out of stock. DiscountVapers lists them on their site but who knows when they will get them in stock. I loved the Protank for the 4 days I had it, but they have do something about that base. It broke off in my eGo ( I was using it on my MVP but it stopped firing, most likely because the thread was coming loose and wouldn't make connection.
