I recently bought a very expensive (for me, at least....$120) squonking rda, and went and got a Kanger Dripbox 160 for it. I actually like it a lot more than I expected to...the board and display are very nice, but it's a brick in the hand, like a reuleaux. I wasn't sure if I"d like squonking or not, but I do. I'm happy to have the two batteries and vv, but I'd like a single batt mech squonk too.
