These Vargo Triad Ti stoves look sexy, but work like crap. Don’t waste your time buying and returning it! =( I tried one of these out in 2008 and was disappointed. I figured they might have improved it since then so I bought another at MEC.ca.
I filled it with methyl hydrate which is the easiest alcohol fuel for me to source. Lighting it was no problem, but even with a windscreen and inside my garage it was unable to boil 2.5 cups of water that I typically need to rehydrate a camp meal. The water ended up warm, but not boiling.
With my usual Trangia burner I can boil that much water for a meal and if I am lucky boil another cup for tea.
I’ll go back to using my trusty Trangia and try some of the DIY beer can stoves for an ultralight option. This Triad is going back to MEC and I won’t waste my time trying them again.
