inexpensive Mogelpackung

Good: burning time is quite exactly 60 seconds as promised. Approximately 50% longer than for the "simple" sparklers.
But obviously, the same amount of material thermite were used like this. They burn much listless (with less spark effect) than the 40-second standard candles. And the "igniter" is just slightly roughened thermite at the top of the candle. Good sparklers have at the top a small amount of material for easier hochenzündliches ignite. But: It works the same way!
That leaves: They are longer than standard - mostly by simple wire. They burn longer than standard - but with less spark. I would not buy again. Either standard, which take up less space in your pocket, or real XXL, which are also much more expensive. Who just the longer focal length needs: access. And: It was promised in the product description otherwise. Therefore, and I may just pull off a star burn for listless.
