I bought this stove a month ago and tried it several times in my backyard with my Kelly Kettle. I wasn't impressed by the first and second runs. It turns out there is a break in period. My third run with it was amazing. The stove produced huge jets and lots of energy. I was able to boil 1 liter of water in my Kelly Kettle under 5 min. I own out-d Chinese stove and another one similar to Trangia and It takes much longer (up to 30 min) to boil 1 liter of water with them. White box stove is a fire beast!
