I had a critical BRS fail while backpacking last month. Temps in the 40's, elevation 5-6,000 ft, minimal wind and a new full canister (which I tested prior to, and after the outing). After a couple minutes the stove just stopped "passing gas," even when opened up all the way. When I tried the stove again at the end of the day, the same thing happened again. Looked for, but didn't observe any obvious blockages with the canister or stove. Won't trust it again - at least it's only an $18 loss, and the only fallout from the experience was some lukewarm breakfast and dinner. As luck would have it, the Soto Amicus appeared on Massdrop right after I returned (just missed the Windmaster)! I'll gladly pack the extra ounce and a half for a little reliability.
