Oh and I'm all Kanger Evod. I'm not necessarily loyal to that, but it's what I got started on. There is so much equipment out there that I don't even know where to go next. I have 4 standard Kanger Evod batteries - two 650ma and two 1000ma. I have one Kanger Twist, but it burns out all my coils even at 3.8 volts and 2.5 ohms so I don't really use that one anymore.
