I don't think I'm ever going back.
Up until this point I have exclusively used a Whisper-light international. I really liked the fact that it was multi fuel. I was never too impressed with it, it just worked. I figured I'd give this a try on a recent trip when I was looking to save some weight. Oh man this little guy blew me away! Boil times of about half of my old whisper. Super small and packable, it fits with a canister in my GSI cook set. The only downside to the canister stoves is that you need to know how much fuel to bring. A small price for how well this works. I don't think I'll ever go back to a liquid fuel stove.
