I have used this stove on multiple backpacking trips and one tablet provides enough heat to boil two cups of water. I have used it in near-freezing temperatures. I mainly got it so I could fly to a destination since airlines don't like liquid or gas fuel on their planes and the places I go do not offer refills for my gas stove so I have to take my own.
The fuel tabs will leave a residue on you
