I would like to use these, but when I researched them a little over a year ago, I found that FlameKing, who made the ones available at the time, had a massive recall sometime prior to 2020 for safety issues. I also found a number of peoples comments about using these and having the valves leak.
For quite a while, you couldn’t buy these anywhere in places that used to carry them, for instance REI, dropped them.
I never knew if the problems were with the older versions and there’s a newer version that’s safer available or not. Does anybody have any further information on that?
