i use a butane lighter all the time and it takes probably 15 seconds to light these and they stay lit for a long time! i usually get the 50 piece set of these every roll that i have used there has not been one broken coal inside - they do smell a little bit but after you get the coal lit and ready the smoke goes away i would say a wonderful coal to use.
My favorite coals so far - I like the coals to light fast and they have never broken in half for me before and I've been using them for about six months - These are Golden coals are the best choice for instant light coals - !
They heated just fine but the first roll i opened almost every other piece broke in half in the heating process - Haven't opened the other four -
