Many of my boy scouts have one. I bought one for the troop with the 1.5 liter pot. We just use it to boil water, so it works great with that. I haven't had any problems with boiling water. It is easy to use, and easy for boy scouts. I have had a hard time getting it to maintain a flame when I try and simmer. I am looking at getting a gigapower though.
