Super reliable in all conditions
I originally looked into getting a Jetboil to go along with my pocket rocket but stumbled upon the windburner. It seemed to have a similar design to the Jetboil, with the added advantage of being nearly windproof. While the jetboil is theoretically the most efficient stove at boiling water, it only does so under ideal conditions. Wind drastically changes the boil time. The windburner is unaffected by wind and so is great for real-world use out in the field. It borrows technology from the MSR Reactor, which is a snow melting powerhouse. So you could also use this as a winter stove for melting snow!
There's only a few drawbacks with this stove. First off, it gets WAY too hot to do any real cooking. It's made solely for boiling water, and maybe soups if you're attentive and stir constantly to ensure nothing burns on the bottom. Second, it doesn't have a built in igniter. In really windy conditions, it can be tough to get it lit. But once it's lit and the pot is on, it's basically unstoppable. Lastly, and this one is minor, but the lid has a weird fit. It doesnt seem to fully snap on and it just irks my OCD. I've inspected other units and found this problem on all of them.
Overall, a great stove if you're willing to carry a few extra ounces for something super reliable and efficient at boiling water.
