I read "The Naked Whiz" review of the Kingsford Charwood before I bought it. The review indicated that the Kingsford Charwood was okay but not great. I tried it anyway as Lump charcoal is hard to find in Fairbanks, Alaska. I was not pleased with it. I did find some plastic "twine" in my bag just like the "twine" in "The Naked Whiz" review. It sparked a lot and seemed to burn pretty quick.
I would only use this again if it was the only lump I could find but doubt I will ever be in that situation again!!
