I've got the (steampunk) Tesla Nano 120. Fast firing mod and love the mechanical on/off switch. Also got some Invader III s. Great, hard hitting VV mods without a screen but with a potentiometer. Cool design - only downside is 24mm attys overhang. I don't use dual battery mods much these days but still rate those.I had to think about it too and remembered I bought a couple of the Punk 86w tube mods.
