Very good stove. It can be turned down to simmer low enough to keep from burning your noodles, or cranked up to boil cod water in just a few minutes. Used it on an 8 day self supported bike packing adventure in B.C. My partner had a Snow Peak GigaPower, also with an auto ignitor, and we did several two pot meals, so I got a good comparison. My thoughts: Both light easily. The GigaPower is smaller and comes with a little plastic case like the Pocket Rocket (which would probably be a better comparison)and is lighter than the Superfly, but you already knew that. The SuperFly simmers better. We got some onions burn-stuck to the bottom of the pan with the GigaPower, but never with the SuperFly. Both are impressive at full power, but the GigaPower boils water faster. I like the fuel control valve better on the MSR than the GigaPower, it feels more positive when shutting it off, and it folds up better. After a few uses the MSR's pot supports start to warp and become more difficult to swivel together, where the GigaPower's swivels are under the fire and therefore don't warp as bad. The SuperFly has a frightening habit of leaking gas when unscrewing it. I hate to say it, but this was designed to fit pretty much any canister, and it does - we used the Snow Peak ProIso canisters for both - but the one size fits all downside is that it doesn't fit as well as a purpose built screw-on fitting. If you are quick you can minimize the fuel leaking when unscrewing, but this trait was unsettling to me, especially when you forget and are taking this down when another stove is burning. Thankfully no fire ball erupted, but think before you dismantle. The final words: Good stove if you like to get gourmet in the woods. Simmers better than some others on the market and starts reliably. Take care when packing up and enjoy!
