Jim..
looking again at the close up of the stove/burner head i see that it's a "heavy"duty item.the castings,nut,bolts,flame spreader attachments and so on look like they are made to last
Yes, my impression exactly.
I took it out again today. I dragged the pot around on the pot supports. On the old PR, I got "chatter" from the thin pot supports as the weight of the pot moved them and then let go.
I got no "chatter" from the MicroRocket.
