Tried Humphrey charcoal first to cook some steaks. I started the coals and walked away to give em enough time to heat up. I came back after a while and the thermometer turned all the way around and read 100 degrees!!! I've never achieved that high temp before. In fact, I thoroughly burped the thing and still singed about half the hair off my forearm. As if the incredibly high temp wasn't enough to make a believer out of you, try low and slow with it. I smoked a butt overnight at 225 for 19 hours and had an incredible amount of lump left. I can't express enough how pleased I am with this stuff. I used to love royal oak, but think I found my new favorite!
