Haven't done a low and slow with it yet, will be doing this weekend. There is a guy (not the Whiz) who used 16.5 lbs @ 225 and ran for 85 hours. As soon as I do a low and slow with it I'll post my thoughts.
This stuff is from a different dist. and manufacture than Kamado; it's from Komodo Kamado which has no relationship with Kamado. When they got into the ECC business they were very aware of the issues with the post 2003 (I think) Kamado ECC. The Whiz has not reviewed this charcoal due to the fact that it turned out not being what the distributor ordered, and is waiting for the correct shipment to arrive. That said, many other's have used it and written their own reviews and have been quite satisfied, which is why I bought so much. Also he discounted this stuff as it isn't what he originally ordered.
Mark, this stuff is from the manufacture of the original Kamado ECC you're referring to.
If you go to the Komodo Kamado website you can find information on purchasing and the story behind this shipment and the new shipment. There are a couple comments from The Whiz regarding his first impression of it and his "non-review."
