I have had numerous failures over the years. I think I have tried all of the brands. The last one quit on me during a spring turkey hunt on the North Rim. Night time temps in the teens and no propane flow. I had to hot foot it to Flagstaff for a replacement. Wasted a whole day of hunting.
I then did what always seems to work. When I got home, I purchased a spare on ebay for half what I paid in Flag. Since I now carry it everywhere, I expect I will never need it.
This has been working great. I believe the one I last replaced is working longer than any of the others did.
