Thanks for the input. Between better efficiency and more volume vs. my 700 ml pot, this kettle seems like a good option now that my kids are going out with me sometimes.
I tried the Minibull stove from energy drink cans that used the priming cup, but never had good luck with getting it to catch. It doesn't seem to be on his website anymore. I've seen the discussions that mention the need for longer priming, but it was starting to really eat into the fuel consumption and was basically just a pain.
