GotVapes VISION ViVi NOVA™ 3.5ml V2.5 REBUILDABLE TANK
[gv-VIVINOVA-TANKV2.5]

The tanks work great. The problem I have with them is the threading. In four diffrent mods the threading was so shallow the tank would wobble inside the the 510 fitting. Doesn't seem like an issue except it was enough of a wobble, and the threads are so shallow, that the tank could actually be worked lose from sitting in my car console driving. It would tweak it self so that it would become cross threaded. I am worried it will end up stripping the fitting on one of my mods one day.
