They have the ZAP on the ProVape site but it is made in limited quantities and release for sale is announced on FB about every 4 weeks. I'm using ViVi Nova on my ProVari and it vapes real well with a 60/40 pg/vg mix ratio, but I'm waiting for the ZAP myself, a buddy of mine purchaced one and let me toot it...it's amazing. Great addition to the Vari.
