A sophia is basically a rebuildable replacement for a carto that works in a billett box or carto
tank. A Diver is another version though not as well liked.
Thanks, Myrany. I hadn't heard of a Sophia or Diver until I got a BB, last year. Cartos were before my (
vaping) time. I didn't know these attys could be used in a carto
tank. Cool! BB'ers liked the Sophia, but said it was dicey to build, and didn't produce enough flavor. Most who used one went back to the Billet Bridge and BVC coil. The Uno seems to address the concerns noted with the Sophia. I'm hoping it's the bomb; I'd love to stop stockpiling BVC coils!
What is the deal with all of these mods and tanks going mini or nano? I like a big tank and a hefty mod, just me.

If you're referring to the BB, it actually holds a whopping 6 mls of juice! That's one of the things I love about it. And the thing is indestructible. And cute

. But it's definitely a throwback. VV, from 4 to 6 volts, in small increments. No read outs of any kind. Not suited for sub ohm or direct lung. Push button; vape; smile.
Let me know how you like it. I need to know it really, really good and easy to use before I put out that much money. But, it does look promising.
I will, Dancing. I debated, given the cost, and then decided to give it a go. Beckdg's review put me over the edge, especially when he said it was
too flavorful. That's an oxymoron, in my world!
