I don't have the Killer (ordered one, but has not come yet), but I just received the Diver. The Diver is the size of a regular carto (not XL), with a small hole that feeds the rebuildable wick. Wick is rather easy to build, with or without no-resistance wire, although the ceramic cup is quite a small space to work in. I am
vaping through my first tank with the Diver right now, and so far it's pretty good but not perfect: very nice when it feeds well, but it get sometimes flooded, and I also get some dry hits. It seems difficult to control the
juice flow. But this my first try, so I'm sure I will get better at it
From what I understand, the Killer has a juice-flow control, very much like the Oddysseus or Penelope, so it is probably a better device. I'll let you know when i get mine. Hope that helps.
