SOTO
Score 8.9 / 10
Average of substance, design, and value.
Micro-regulator and recessed burner hold a five-minute boil in 25-30 mph wind; seven years and 5,000 independent test miles report no clogging and a working piezo throughout.
$70 typical
Its extra cost over basic burners buys a micro-regulator, a cupped/rimmed burner that protects heat transfer, dependable piezo layout, and interchangeable broad or light pot supports—not cosmetic branding.
Resists corrosion and heat distortion better than ultra-minimal thin titanium assemblies.

Treeline measured 8.5 L boiled per 100 g and notes its wind performance protects real-trip fuel use.
This product: 10 out of 10
A compact, unusually quiet object with a low pot-to-burner gap. The removable 4Flex is exceptionally secure; the lighter TriFlex makes packing neater but is less reassuring with broad pots.
Excellent long-use evidence: a seven-year/5,000-mile test reports no clogging and functioning piezo. Carry a lighter and inspect/replace seals when worn; the removable supports are the part most easily lost.
