I've been using 4 or 5 these stoves for at least 10 years with my Scout troop for backpacking. For a while, up until 5 years ago or so, Brunton sold them under their brand as 'Raptor'.
They're tiny and weigh next to nothing. Mine is always in my cook-kit , ready to go. No problem fitting it inside the nested pots with the usual cook-kit pot lifter 'n' stuff. Simmering performance is very good . The ignitor is very handy, but the it is the one weak link. If you drop it in a creek, the ignitor quits. You can still light it with a match, though.
If you need a tiny, bombproof low-cost stove, you can't go wrong.
