Great stove but...
I used this stove on a 300 mile thru hike on the Long Trail in VT. I like how little and user friendly it is. I mainly used it to boil water but it seems to simmer pretty well. You might not want to make cheese fondue in it :)
The only thing I can think of is the lack of wind protection. I should have bought the wind screen for my trip. Overall its one of the best lighweight stove for backpacking.
