Darren, you got the cheap English version. I light a full chimney using one cube in 15-20 minutes and I place the cube on the charcoal grate of my grill.
I've never been a fan of the Weber starter cubes. They're expensive and they don't burn for very long. I really like these:
I get them at Fresh Market, for something like $5.99 for a bag of 72. One of these burns a long time, and it burns hot. Enough to get a full chimney going in 15 minutes. And at less than half the unit cost of the Weber starters, it's a good deal.
Interesting thread as I've been using the cubes for a couple years. I generally only use one. As I only have a Smokey Joe and a smaller chimney starter, I have sometimes tried cutting a cube in half with varying results. It works but is generally more prone to wind gusts. I find they are usually pretty cheap at Home Depot anyway, so I have since stocked up on them.
The main thing I like about the cubes is there is far less smoke than newspaper. I live in a condo apartment with a small patio facing the street and only a partial brick wall between me and my neighbor. In an effort not to produce too much smoke, I use these and I find they work well. They also burn most consistently. They are also safer to handle.
I do another trick in tandem where I put a single layer of Match-Light (or equivalent) instant-light briquettes at the bottom of the chimney so they light first and faster. I fill the remainder of the chimney with regular briquettes and/or lump, including unburned coals sifted out & recovered from from my previous grill session.
I have also tried the Tumbleweeds Firestarters; they produce too much smoke for home use, and have a lot of splinters. I used one outdoors at a park and splintered my fingers, and haven't really used them since.
I'm a two cube guy
I never use the starter cubes......
