I like the fuel tabs - tough, versatile, and hot, but I don't care for the "stove" - rather clunky and needlessly heavy. You can make far better units from discarded aluminum cans. This is just one more way of paring down the weight of EDC kits.
This my first time trying a stove like this. On the bright side, I have several boxes of various kinds of fuel tablets I managed to acquire somewhere.
I suspect 3 rocks arranged appropriately would work almost as well. Maybe even 3 small piles of dirt.
I did not like that I was unable to light the tablets with a ferro rod.
