I love the Weber Cubes. I have never used more than one. I place 1 Cube in a Tuna Fish can, and light it with a match. Set the Chimney over it, and off it goes.
I store my cubes in a plastic storage box abovt the size of a tennis shoe box, with a box of matchs.
The price is cheap, between $3.29 and $4.99 depending on where you buy them, for a 24 pack.
