Has anyone used Black Diamond CharWood? If so is it a better buy?

I just tried this product and was impressed with the lack of odd shaped pieces i always get from other lump charcoals. I have cooked two times so far, put the flames out and still using the same charcoal. I never knew before that this could be done, had always just tossed the leftover charcoal from the previous grillings. So already just with a learned technique, I'm saving money. ;-)
