James ★★★★★ Aug 24, 2026

Boiled water noticeably faster than the cheap butane cans I used to carry, and the fuel burned completely clean with zero soot on my pot bottom. The 450g size lasted me a full five-day trip with two hot meals a day, which was exactly the reliability I needed.

The smaller 110g canister is perfect for a weekend trip, and the valve threads on seamlessly with my stove every time. Boils water fast and burns clean enough that my pot bottom doesn't get that nasty black soot.

I’ve used a lot of canister fuels over the years, and this one burns consistently hot even when it’s half empty. The 450g size lasted me a full five-day trip with two meals a day, which was more than enough.
