Hi felllow Gotvapiens! Max CS Manager for Gotvapes Here. I got the VFate from Danno so I could run some test's on the compatibility of the heads. What I have found is that the heads are completely interchangeable. The VFate dual coil heads will work in a Vivi Nova and the Vivi Nova single coil heads work just fine in the VFate. So you will have multiple choices in heads now, whether you use the Excellent Vivi Nova or the New Spectacular VFate Glass tank. Oh, and on another Plus side. As most of you Provari owners know it is difficult to use the Vivi Nova on it without an Airflow controller due to the recessed 510 connector on the Provari. On the new VFate the 510 stem seems to be just a tad longer giving you a nice air gap on the Provari. Remember, If you have questions or need help come see me at igotvapes.com, Cheers! and as always- vape Well and vape Safe!
