You can light quicklights fast but there are a lot of chemicals in the coal. My experience so far with quicklights are bad because the ones that i had where ashing much and it had a bad taste. Naturals such as Coco nara's or ******* hookah coals last longer and dont have chemicals but are harder to light. you need a stove to light them. Since i used naturals for the first time i never go back to quicklights.
Hope this helped you
