Two of my stoves failed, non catastrophically
Soto Windmaster:

The part of the arm that’s over the flame has been melted and turned to ash. Enough remains it still works. I think I’ll just ignore this. Probably doesn’t make any difference. Maybe some day my pot will be heating along and suddenly collapse.
And then my MSR Pocket Rocket Deluxe piezo ignitor sometimes doesn’t work.
If you unscrew the head, pull it off, then carefully put it back with the tube over the wire from the piezo, then it started working again.
Except another time that didn’t work. Piezo failed to ignite. No big deal, I used lighter. Then, the next time it started working again.
I have heard other people report this failure also, piezo unreliable on Pocket Rocket Deluxe
I have also heard this complaint about piezos in general, they eventually fail, don’t bother with them. Maybe this MSR stove experience confirms that, but it’s sure convenient when it works.
The piezo on the Soto works reliably.
