Just got a Blastmatch the other dayand I tried it out last week on a hike. The trioxane caught the first time. One tab (one third of a block) gives plenty of time to get your fire started, assuming you have the proper amount of dry kindling. If your tinder is dry, a few shavings are enough. It certainly allows fire-making more certain than using field tinder alone.
I include Trioxane in my kit for both fire making and fuel for an Esbit stove.
