Brought this little guy (instead of MSR whisperlite to save weight) for a short overnight trip in the past few days. Worked like a charm with the ground temperature about 5 degree at ~ 3000' elevation. The flame did go weaker overtime due to the lack of insinuation between the canister and ground. Warming up the canister with hand quickly revived the flame and speed up the boiling time.
