After a first failed attempt, it was thought that we were misled. Actually not at all! simply follow the instructions and secure the fuel. Although "inflate" the lantern before lighting not holding the frame so that the paper comes off well. We light, we expect 2 - 3min and loose (it feels when the lantern is ready to fly) One could admire in the sky for about ten minutes, she'll very high !!!!!! it is superb!
