We use one of these while competing all the time.
The regular size chimney starter is too big to fit in the Jambo door.
THIS one, however, works nicely.
In general, I thought it was pretty much a waste of more money originally.
My thought was, "If I want to light less charcoal, I don't need a smaller chimney to do that."
BUT, never thought that my "standard sized" one would be too big, but it is indeed (at least for lighting the Jambo).
