At another forum someone posted a link to a video showing what appears to be a similar stove failing because of the walls collapsing.
Looking at one of the clips I noticed that the other stove was much larger (probably about 4x) and the guy had a veritable furnace going in there.
So keep in mind the size of mine and that there are several types of stainless steel (and wall thickness) used for these kind of trays. (IE, try several time at home before you take it to the forest...)
BTW, they are not cake/bread trays .
I did another test, this time over an hour of as hot burn as I could get . Still fine.
However it takes about 20 min to boil 500ml of water.
Having the right size 'logs" it needs to be fed once every 15 min or so.
Do keep in mind that it is for campers not hikers. There are a lot easier/lighter/faster solution if all you want is to cook over wood.
The Caldera Inferno or the Bushbuddy are both a working LW solution for that.
