They are not that bad to use but when they burn down they burn down to nothing. I've never really tried slow cooking with them so I guess we can see how they work. I would guess they would give a better taste then traditional charcoal. Its funny because you will get pieces of wood that you can tell was scraps from hard wood floors. I have a Weber charcoal grill and just this past Sunday purchased a new gas grill. Check out this grill I got.
