Rating: 4 / 5
I'm torn between giving it a 4 and giving it a 5. It's damned heavy. That's the niche it fits into, but still, with so many lightweight stoves out there that pack better than this it doesn't compare as well to the competition as perhaps it once did.
I suspect if I put a hardcover book on it and stood on it, it would hold my weight.
I've had this stove about 9 years now, I haven't used it all that much because it is heavy, but I like having it and will likely keep it until I die. Why? Because unlike my gas canister stoves, if it hasn't undergone unreasonable abuse I'm confident I can fix it.
At some point I'll buy a second pump, that's perhaps the weakest link in the chain. Some people speak negatively of the plastic pump - apparently if you stand on it, it can break. Don't stand on it then.
(For note, the packed weight of the XGK is advertised at 490g, a second pump would add 69g to that, and the expedition service kit ~90g).
The only negative experience with my XGK I had was when the pump started leaking because of a oring. Curiously it seems the red orings are regular black orings, but painted. That paint had flaked off and was causing a bad seal. I didn't even replace that oring, I just cleaned off the red flakes and all was well. The thing is old, orings are disposable, so its a trivial complaint - but I don't really understand why they bother with the red orings.
I sort of feel every house should have one, sure you'll mostly just take the jetboil on trips instead because its easier and lighter, but I've always considered the stove as double duty heavy-camping stove and civil emergency stove.
