Burned in four-hour sessions as recommended. Wick trimmed to 1/4 inch before every session. Same room (dining, 68°F), same table, no drafts. Kitchen timer, log sheet, two witnesses for the final session.
Total: 49 hours, 52 minutes. The label says 50 hours.
At $48 for 3,000 minutes, I am owed 12.8 cents. I am not interested in the money. I am interested in the minutes.
