In reply to UKC/UKH Gear:
Yes, very good for alpine bivvies. Lightweight, doesn't take up much space and very quiet, plus a handy auto ignition button (matches etc work as well of course, should the button fail). Obviously heavier and bulkier than a pocket rocket but more efficient. I think MSR have a stove which is even more efficient but I haven't had an opportunity to test them side by side. Would be nice to have a wider cooking pot attachment which would fit a 230ml gas cartridge inside.
