I own a Vargo but have only used it once. It didn’t seem to hold enough alcohol to bring a cup of water to a boil (maybe I needed a windscreen?) In my opinion it sucks as an alcohol stove. However, that stove can be turned over to burn Esbit which worked considerably better for me. Esbit is light, cannot spill, and can be added to the stove while it is going.
