I just recently sold off my ProVari. That was my last non-GG mod. Two GGTS, two GGTB, two Penelope, Odysseus and UFS. Stealth, iatty and Ithaka on the way. With CR123 batteries for 6v vaping I have no need for VV. it's either 3.7 or 6v for me. I love building my own coils and customizing my vape...
