Tor H�vard S.wrote a review of MSR XGK EX Multi-Fuel Stove on March 27, 2011
Well, the reviews says it all. This burner is one of the best on the market. I have used it on the high mountains in Scandinavia, the desert in Afghanistan (The sand didn't make any problems) and at sea. The only minus I can see is that it only fits the original MSR fuel bottles. My last stove was an Optimus Nova +, and I had to buy a new bulk of bottles.
All in all: You get what you pay.
