Yep, I can make a fire with just the striker and one of the tinders (no lighter fluid needed) in two strikes. Handy little gizmo. Don't try and take them on a commercial flight.
I've used up all my tinders and had to get replacements. Good thing they are fairly common now.
If you are not careful, it's possible to set your fingers afire if you charge the recepacle with lighter fluid. I determined that the fluid wasn't necessary so long as I had the tinders, and have not used any more since. Without the tinders, the fluid would be a great help for starting less effective tinder types.
