Heat exchanged for improved fuel efficiency and boil time. an make a significant difference in the amount of fuel you use- (up to around 25% less is not uncommon). Fits all MSR 1.5 and 2 Litre pans (except for the 2L Titan pan.
On longer trips the increased fuel efficiency of using the heat exchanger will almost certainly offset the extra weight of carrying it.
