Jim..i made a comment at CCS but 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 and not a knock off thats made to look like a stove with a short working life.i have one of those small burners in the orange box that i carry in my PFD thats a "use once and toss" survival item like a foil blanket.
