As others have said, a great little stove. I' d just like to add a neat little trick to reduce additional pumping during cooking. Buy the 30 oz MSR fuel container and fill it up half way leaving the remaining space for pressurized air. Keep pumping until you feel resistance and you will be able to cook for at lest 45 minutes.
I cannot believe that this is even possible. Let me paint you an image. 20 deg F, tee shirt, light fleece and my Montane Anti-Freeze. I was sweating. Need I say more? Why this brand is not known in this country is a total mystery to me.
