Review on UST Wayfinder Lighter: Orange Piezo-Electric Ignition with Built-In Compass for Backpacking, Hunting, and Hiking by Jim Bodnarchek

This is a butane lighter. This design was passed from manufacturer to manufacturer. This is a good piezo lighter. The flame is hot but short. You will need to adjust the fuel supply screw on the bottom of the lighter for your local altitude. You must keep this lighter in an inside pocket of your clothing. If you're out in the cold wearing this on your EDC keychain you'll be disappointed. [Personally, I add a peanut lighter and iron rod to my device ring (where I keep my keys).]
