This stove is not reliable. It will break after 3 - 4 uses.
My wife is on an 8-week research trip in the Mojave desert with this stove. The pump fell apart after 3 uses leaving her unable to cook food.
I drove 1100 miles to bring a replacement stove to her, and the next AM we started to cook some eggs and the new stove failed. The hose that delivers the fuel was somehow plunged. I was using new fuel and brand new fuel cans.
DO NOT buy this stove. It will fail. Look at MSR stoves.
