Try running the vivi 510 connector on a fine grit sandpaper. Should make better contact.
EDIT: looked at glory vapes and its not a vision. my real vision large nova reads with 2 decimal places on the side like 2.80, 2.10 etc and the capitolization is Vivi Nova, not "ViVi" but like i said they work just as good IMHO and havent had any leaking with my cheap minis
i now have two different versions in my possession. The ones from madvapes say vision on the box, the other doesn't. The ones from madvapes have 2 decimal places and a weird cap to the atty, and a white ring around the coil. The threading on the top cap seems slightly longer, but it still says "Vivi Nova" not "ViVi Nova". I don't know. Honestly, i don't really care at this point.
What's being discussed is the connector issue...so that's why he named the device and the tank.
Otherwise, the device should be largely irrelevant. Whatever PV is just applying power to the coil. Now, that said, there's a lot of VN knock-offs that seem to have issues. I've had zero issues with the VN so far, other than user issues that I would expect (not wrapping my own coil properly or SS mesh shorts while experimenting/tinkering).
Some have reported that the silicone top cap chokes the wicks and had to be trimmed a bit. Other have used 100% VG juice, had wicking issues, and blamed the VN (duh). A few have reported leaks (I've NEVER had a leak with it...go figure).
Do you have a specific question? Maybe start a thread?
