now that I had bought myself a new shisha I wanted to have a decent charcoal. the self-igniting I had become tired, because you are constantly the coal out schmeck there and it begins to scratch. in this coal is not so. it glows very long and hence the entire tobacco is smoked, not just half. The only downside is that you have to burn this coal with a gas burner. I love to be taken but this purchase :) very satisfied!
