I bought the micro as a back up stove for mountaineering, not even planning on using it. On a recent trip up Rainier while sitting at Muir melting snow with my Dragonfly stove I decided to try out the Micro.DANG this thing is awesome! I filled up a Backcountry 750ml Ti pot with snow and opened the micro up all the way. It took the Micro no time at all at 10,200ft to melt the snow and bring it to a rolling boil. I was amazed! This will be my go to stove for soloing and fast and light adventures.
