Took this out at -15°F on a Boundary Waters trip and it primed on the first few pumps when my old pump would've been useless. The metal body feels solid without adding much weight to my pack.

The priming action stays smooth even when the thermometer reads -15°F, and that's something I genuinely didn't expect after struggling with other pumps. Fuel flow stayed consistent through three days of subzero camping, no frozen o-rings or stiff plunger. It's the kind of gear you stop thinking abou

Used it on an overnight ice-fishing hut trip when the thermometer read -25°F. The pump never hesitated, and I didn't have to baby it or fiddle with the valve once. That steady flow in deep cold is exactly what I was hoping for.
