I'm #168(or169?)! Got it as a surprise gift from my Dad two days before a 3 day trip in Oregon. It rained the entire time (yeah Oregon!), and so spent a lot of time under shelter in the morning and at night. I went with some backingpacking beginners that wanted to try to make a fire. That didn't go very well, as I only had a RAT Izula with me for splitting wood, but it made PLENTY of wood for the Boiler! I was a little nervous about using it in such wet conditions, but finding some fresh deadfall wasn't to bad. The efficiency of the boiler was awesome. Boiled 4 cups with just a small section of a 2" branch. I used my knife to baton the wood into quarters, which made getting the wet bark and moss off much easier. I made some feather sticks to be my kindling, and used a tiny piece of a PJ soaked cotton ball (which I keep inside short segments of straws with the ends melted) to get it going.
Only downside is the smell in the pack, but I didn't notice it passing on to anything else, though this was a short trip.
I had a gigastove with me, and it's much more convenient in the rain, but I had more people than I anticipated that I was boiling water for, so having the boiler with me was nice insurance. I had both stoves going at the same time!
