These bad boys are the greatest invention since the chimney starter. Actually, you're supposed to use them in conjunction with your chimney starter.

For the past several summers, when I go to light my charcoal grill I spend about 5 or 10 minutes keeping the fire going underneath the chimney starter so that my charcoal lights and ashes properly. About a month ago I came across these lighter cubes while at Lowe's and they are like a gift from heaven. You place one underneath your chimney starter, light it, and you're done. They're cheap and they save a ton of time and energy to get your charcoal going.
