I haven't the faintest notion. I doubt I can find them all. I like variety of flavors, so there are currently on 6 rigs sitting on my desk. And one in the kitchen, in case I need a vape in there. And one (or three or maybe six, haven't looked lately) on the nightstand in case I had one in my hand when I went to bed, or wake up in the middle of the night and need a vape. And one in the bathroom, in case I need a vape in there. And out in the workshop, I know there's several on the bench, plus (at least) one in the holster I built on the table saw. And on the drill press. And the chop saw. And there's at least two, plus an emergency backup, plus spare batteries and juice in the "traveling" tool box. I doubt there's more than two or three in my car, as many more won't fit in the cup holders. I'm pretty sure of a round half-dozen at work, plus juice and batteries and a charger. And then there's those two or three boxes of vape gear I haven't even opened since I last moved; Lord only knows what might be in there. And then there's one or two on the slow boat from China that haven't even got here yet. Plus a bid or two on some authentics I don't yet have in my collection on eBay. And an authentic Nemesis sitting in my shopping cart at Atmomixani, waiting on the next paycheck with an excessive amount of overtime. And a note on my keyboard to order a new Troy II (or two) as soon as Fakir's Mods gets their website running again. And I have recently decided I can't live without two or three more copies of the Serpent SMM, as it has recently become my favorite single-coil tank, just as soon as I get my rountuit all polished up. You get the idea.
