I purchased this system at the end of March for our thru-hike of the Appalachian Trail. The compact, self-contained design was appealing, as was the heat exchanger on the pot which we figured would save fuel. It worked well for the first couple of weeks as long as it wasn't windy.
Over the course of several days, however, its performance rapidly decreased and it eventually stopped working entirely. I confirmed that the fuel was getting from the canister and past the stove valve, so it's a clogged jet that is causing the problem. We haven't had any boil overs and have only boiled water, so I know it's not food or something in there. I have cleaned the jets on white gas stoves using a thin wire, but the design of the Stash only provides access to the jet through one of the four very small holes on the side--and my little tool doesn't fit. We have been eating freeze-dried dinners reconstituted with cold water, which is less than idea. Next time I have the opportunity, I will try to get a needle-threader (which has a very fine wire) and see if I can get it in there.
I contacted Jetboil support for warranty help. They were very nice, but want me to send the product in for evaluation--which obviously isn't going to work while we're on the trail. I wish I had gone with the MSR or SOTO like everybody else on the trail.
