I use a Colibri Quantum lighter, and started having trouble with it working. It would sputter and not hold a good flame, and I have always used colibri butane. I mentioned this to a friend who introduce me to Volcano Lava, which is a quintuple refined butane. After several fillings and ventings, as recomended, the lighter is working great again. Have any of you guys had a good or bad experience with a brand of butane? Does anyone else use the lava butane, and does it seem to burn better?
